Tackled this project last weekend and into the week a few nights, what a pain in the rear!! I would be just fine if I didn’t have to do that again for a long long time!
If there’s a way to do that completely from inside the car, I’d love to see it! I messed around with it for quite sometime, before finally taking the fender completely off. There’s just no way with them angled tubes on a non ac car that I could see possible. Hard to believe that was the best design they could come up with in 1968, but oh well, done now, have heat again! Thanks for everyone’s help!
Years ago I had to fix my core on my coupe. I cut the opening in the core cover larger so I could get the angled tubes in without buggering the soldered tubes. I had to take that leaking core out at least 2 times. Make sure the core tubes do not touch the block. Not a fun job. The guy that owned my vert before me cut the inside wheel well on the passenger side so he could access the core, A/C. fan etc. I decided to leave it that way. I worked for me because the heating failed (wiring) and I had to access the fan and wiring in order to fix it. Fender and hood stays on.
