Can I get some clarification please.
« on: September 16, 2023, 05:58:13 AM »
After searching and searching and rabbit holing on several threads here for 45 minutes, I give up.
How was this seal applied?
Pre assembly and adhesive before delivery to the assembly line??
Pre assembly and clips before the assembly line?
Thereís no indication to ďremove adhesive backingĒ
Thank you in advance.

Itís held on with clips. The later core supports are pierced with holes across the top to push the clips into. Non-AC cars have dimples where the holes are. Non of the repro seals have aprovision for the clips/ pegs. Tough to findÖ

There was also a thick dense foam seal (3 pieces) between the radiator and core support (2 up top and 1 across the bottom IIRC). Iíve only witnessed it on my old 69 and when restoring the 1st pacer of my fathers we used them from my car on his.  Idk if I have seen them in repo form but Iíve also not looked recently.  That is whatís being called out as #2 in the AIM.  #1 is the top seal for the core support and hood.

Correct, I have the TSB on this as well. It lists the production dates in 68 when this all started. Iíll dig it outÖ You can see the foam seal in my first pic.

Thanks Steve.
Is the open lip of the seal towards the rear?
Iím wondering if the original seal had adhesive and clips or just clips?
The 69 AIM shows the hole/clip install, so idoes it stand to reason it was installed on the assembly line?
My GM replacement core support from 1993 has dimples, so I surmise itís an either or over the counter application. The pictures definitely help.

Cook-Iíve got the upper and lower seals already installed.

Steve-Fiber optics look nice. I installed mine last year.

I bought the filler foam from e-bay. The guy cuts it from a big sheet. Don't remember the seller....Joe

1968 glued down 69 had the clips. My 1968 06A was glued down. Hope this helps.

68 07E just clips, no glue. Yes, open part of the seal positioned toward the engine.


Go to the Restoration section, see The post on A/C seals from long ago.

Thanks again, but hereís the boggle. The seal appears to be already installed on top of the core support, due to no further instructions in the AIM to remove adhesive backing or anything further. So it would have already been pre installed before assembly line. Yes/No?

David, Read my thoughts over on the other thread. IMHO, the adhesive was never used by the factory on this top core support seal. By the dealer, maybe. Iím still convinced it went i to production w/ clips late June per the TSB.

Wow, wow! Learn something new every time I log on to this group. 51 years owned 69í SS 396 L78, and never knew the radiator support also had a seal kit. Now educate me, is this on all cars, as mineís being a solid lift engine and non A/C. Thought I had all the bases covered on my restoration. Thanks, in advance of an answer.

It was done on the line. AIM clearly says to remove backing. See item #10.
Looks like they changed to the 69 style late in 68.
