Related to the core support - the top rail of the core support has periodic dimples in it, to accommodate for the drilling of holes for the clips for the option of the AC rubber strip - that is mounted to the top of the core support rail.


Any idea during the 67-69 production years/months when the dimples were molded into the core support top rail?

Appreciate the insight into this.

Working on a 68 L78, 03B car - would like to be correct on this.

Could not find anything on the CRG about this .....

Paul, absolutely - i have the dimples in my core support - but someone questioned weather that was correct for early 68 car.......its an ac related need, so i assume all assembly line core supports had the dimples.

thank you

My LA built 68 Z/28 has all original sheet metal & doesn't have dimples. It's an 02E car built on 3/13/1968. I'm pretty sure dimples didn't get used until 1969, but I'll keep watching here....Joe

Hey Ed, I found where I remember reading about it. It's From the 1968 Legends Judging Manual https://i.ibb.co/2391m4xV/IMG-6311.jpg (https://ibb.co/Swj4WCbY)

If we could get some core support numbers off some original, we may be able to narrow it down. Even loose core supports that are 1968 would help. I'll get my number Monday for you. It has no dimples. It will be a start.....Joe
