core support

[GMPARTS]

does anyone know, are the aftermarket core supports identical in every way to a general motors made support?  i'm trying to find out for sure if the aftermaket repops have the dimples for marking the holes for the top a/c seal.  i need this to be accurate. thanks in advance.

GMPARTS,

I apologize for moving a little off your question.  We had a long and interesting discussion about a/c seals on 68s a while back:

Note 68L30's points.

I'd like to know what you think...

And somebody, please answer his real question about the support!

[GMPARTS]

Thanks for the reply lakeholme, i'm trying to identify an original from an aftermarket repop. i'm pretty sure the repops do not have the marking dimples like the oem. can anyone please look at there repop core support and let me know if the dimples are there? they are about five to six inches apart on the top of the panel. thanks!

Only 69s had the dimples, I repaired an original 67 or 68 core support and I had to weld the holes smaller for the voltage regulator (69s used screws and 67-68s used rubber nuts) and used a punch to recreate the dimples.  I had an old 69 one to compare.

Do the repros have the square inset nuts or welded nuts from behind?

i'm trying to identify a core support i purchased. if its not a gm core supt i wont keep it . its in an oer-classic ind. box. the label says 3962940 {gm}   i dont believe the repops have the dimples, but i need someone who has a repop to look at theres. thanks in advance.

3962940 Is the SERVICE replacement part number for 67-69 Camaro...

[GMPARTS]

yes that is true, but still does not help me indentify the one i have.

Repo core support's arn't very good. They dont fit the subframe and the hood latch bracket very well. I fixed my old one. They don't have square weldnuts as original so I guess you could tell from that. At least the one I got didn't.

[GMPARTS]

the one i have does utilize square weld nuts. are you sure the repops don't have the square weld nuts? thanks any input is greatley appreciated.

One of the radiator well nuts was on backwards.  Instead of the radiator resting flat on the core support it was raised up the thickness of the nut.  I fixed it with a sheet metal bolt after knocking the well nut off and welding the hole closed.  I have not had any problems...yet...with the core support fitting the car.  No Dimples.  It's a GoodMark part.

Also the correct holes for the voltage regulator and the horn relay are not even close
