My X's have AC so I have not looked into the 124 core mod, therefore I am only posting this out of general interest.two version of heater core for 124
ThanksWelcome to the forum!
This is only for non AC cars - that is what you have? Check the link Yves added - it has very detailed pics of the mod.
Fill out your sig with your X1/9 details - that will make it easier to respond to questions
I am in the same boat, I just finished pulling my wiring harness then moved onto the HVAC box. I found the heater valve seized and the lever cable disconnected. I saw a kinked heater hose, then discovered that the reason it was kinked, was that the hose was rerouted back into the center console & joined to the return hose! I continued removing the HAVC box and discovered the AC evap. but NO HEATER CORE! It's gone.. completely.My X's have AC so I have not looked into the 124 core mod, therefore I am only posting this out of general interest.
Regarding the two versions of 124 cores, that "early" one seems it may avoid the heater box mods needed to clear the larger "late" one. I see there is a price difference between them on the referenced site, but not so much that it would be worth the ease of installation (assuming it is otherwise the same, as Yves said). Is the early version readily available from the common vendors, or is it more rare? A larger core could offer more heat, but with the tiny cabins on a X that really should not matter - unless you happen to live in a extremely frigid climate.
I'm not too surprised at what you found, old cars like these often get that way.I am in the same boat, I just finished pulling my wiring harness then moved onto the HVAC box.

I've checked MWB, Fiat Plus, Vick and Holland, Monte Hospital, but none have the A/C car heater cores, used or other.
So, I'll try the 45mm thinner old style 124 heater core. I suppose I could rip apart my '71 124 spider dash, to verify fitment, but I really don't want to dig into that now. I'll have to find the in & out coolant elbows and gaskets as well. Not too concerned about minor differences in thickness, that can be compensated with a poly noodle-tube gasket.
I'm hoping the other dimensions and coolant connections are the same?
Thanks for any info!!
Well I discovered more info since I posted this question. I figured the Evap. care and the heater core were stacked, but no. So the "thinner" vs. "thicker" does not apply. The A/C Evap is installed horizontally, in place of the heater core on the later A/C cars. The heater core is then installed vertically, after the fan. I can see the port in & out locations on the HVAC box and the rectangular void where the core should be. I'll have to measure for dimensions and see if the 124 cores will fit. I'll give A-R a call and see if they have the total measurements and not just the thickness.I'm not too surprised at what you found, old cars like these often get that way.
To be clear, as I said I have a AC heater box so I'm not familiar with the mods required to fit the 124 heater core beyond what I've read on the forum (there are a couple of excellent write ups on doing it). So I do not know if the "early" or "late" 124 core is better to use. I was only speculating that the thinner one may be easier to do. Please do some research and verify what would work best for you before buying anything. Or at least don't blame me if you don't.

On a side note, I may need a replacement Evap core anyway, so I was wondering if @lookforjoe could chime in? Did you replace your evap core with a parallel flow version when you went to R134 or did you reuse the serpentine original? I've done an R-134 conversion on my Alfa in the past and was not impressed with the cooling. I'm replacing all the hoses with lined versions this time as the R12 hoses are permeable to R134 and the fittings leak anyway.
Since I'm in Central Florida, and I'd like to use the X year round, proper A/C is of paramount importance. Only the newer cars get used in the 5 months of our "summer". We're on an inverted schedule here, where we park our classics in the summer and bring them out in the winter!
You can fix that. Hussein (@lookforjoe) described it earlier and that is either linked here or elsewhere.Quick question: does anyone have a spare metal "flap" for the top of the box? Mine is rusted solid to its support bar. I'll figure something out, but if anyone has an extra one please do let me know.
Thanks - I tried the heat trick but no luck. The bolts broke off when removing it so looks like I'll be welding again. I'll soak for a few days as suggested.You can fix that. Hussein (@lookforjoe) described it earlier and that is either linked here or elsewhere.
This is the "fresh air" flapper that lifts up into the scuttle. It gets wet there and the flapper rusts to the bar holding it. Remove the flap with the bar (there are two bolts holding it in) then soak in penetrating oil for a few days. You should be able to move it back/forth. I used some heat on it too.
I must be confusing things, wasn't that the seller that recently posted on the forum saying he went out of business because we didn't buy enough from him and we are all a bunch of idiots?I found another source for the heater core. https://www.spiderroadster.com/heating.htm
Yikes!! Not sure if that's the case. I found it online and ordered online easily. I didn't indicate that it was for an X, just ordered the parts and he sent them right away...I must be confusing things, wasn't that the seller that recently posted on the forum saying he went out of business because we didn't buy enough from him and we are all a bunch of idiots?
That's the discussion I was thinking of. Someone in that thread said the original post was from "Spider Roadster", I don't know any details.Here's the thread @Dr.Jeff was talking about: https://xwebforums.com/forum/index.php?threads/new-x1-9-parts.39887/#post-363423
Thanks Hussein, (@lookforjoe) That's what I needed to see. I also found your other posts showing the "gutted" expansion valve and placing the orifice tube in the line where the old accumulator used to be in the frunk. Great idea... If you have a spare core for the heater (A/C style) sure I'll buy it. The hard lines thru the tunnel are OK, but the valve is shot, but I was thinking of putting a plastic generic version back at the source area, and put in a longer adjuster cable next the the accelerator cable, thru the tunnel. All new silicone or rubber hoses goign in anyway. ALSO side note, would you also be willing to sell your old '87-88 style guages, since you don't seem to be using them anymore? I'll be attempting to use the original style set with the K24 swap, I've been digging into tach converters and the cable drive & pulse converters that Dakota Digital makes. There is good info on the K20a.org forums about that. I used one of those pulse converters on my GTV6 when I swapped in an '89 Milano transaxle with a Jeager hall effect sensor to the speedo that used a gear driven pulse (contacts) unit in '84. I really like the larger numbers on the 87-88 and the Oil pressure in lieu of the volt meter on the left side. Post or Message me, plz.Sorry -I didn't get a prompt from your post - I kept the stock core - I also did away with the R/drier & expansion valve - went to orifice tube/accumulator.
