The picture that are attached do not show fastner holes in the front to back arm of this piece. I have seen these pieces with fastner holes (at least 3 and maybe 4) along the the front to back arm. Are ther different trim pieces for the various years of the c-3's particularily the 1968 to 1972 years

There were 3 different center moldings for coupes used over the 68-82 period. 1968 (and, possibly early 1969) was GM #3932952. 1969 through 1974 was GM #3966658. 1975-82 was GM #345446.
The GM #3966658 replaced the GM #3932952 for SERVICE in March, 1970. GM #3966658 was discontinued without supercession in March, 1982.
GM #345446 was discontinued without supercession in October, 1994.In Appreciation of John HinckleyComment

Re: C-3 T-top center trim piece (chrome)
Thanks Joe.
Your answer was helpful. However, I am still at a loss regarding the number of holes in the top of the front to back arm of this trim moulding. The pictures in the alternate url http://jep7900.zoto.com show no holes for the fasteners. However I have seen counter sunk holes on a 1972 coupe. The Corvette parts book does not help. Can you help? I am looking for the correct one for a 1972.

I don't know that ANY of the 3 moldings that I previously described, which cover the entire 68-82 period, have holes in the TOP of the front-to-rear section of the molding. While I cannot say that the one you have piectured is the correct one for a 1972, from the pictures it, at least, APPEARS to be the correct one.In Appreciation of John HinckleyComment

Got AIM??!!...
That is the correct center trim molding for your car.
There are NO holes through the top of the molding, except along the top of the windshield frame (four screws), where "loop" shaped brackets are welded to the top of the windshield frame for attaching the molding.
If you look at the vertical flange on each side of the molding center bar, there are three holes each side to attach the molding to the center bar of the body frame. There are two more screws at the rear, one on each side extension, to attach the molding at the rear. I'm sure the engineers felt that the fewer penetrations through the trim molding to be sealed, the less chance of leaks through the top area.Comment

Re: Got AIM??!!...
Chuck, could you look at Ebay item # 150067942564. What year car do you thing this moulding is from. It does not appear to correct for a 1972. Your thoughts --- www.ebay.com --- for your convenienceComment

Re: Got AIM??!!...
Sorry, I can't help you with what the ebay item is except to say it's not the correct trim for a 72...the molding in your earlier zoto.com is 3966658 which is correct for 69-74 as Joe said.
If I had a pistol to my head, I would guess that it's Joe's 68-maybe early 69 version...it was changed fairly quickly for some reason. My reasoning for that is GM didn't make changes unless it was necessary to improve the product or reduce costs. Those long skinny rear extensions would make that molding more fragile in assembly, and extremely hard to remove in the field without damage; the sealant would act as an adhesive, and in the process of pulling the molding up, I'm fairly confident those flimsy extensions would be buckled and bent making it un-useable.
If I'm right, the evolution would have been to simplify the molding by eliminating the long narrow rear extensions, and replace them with the separate roof trim pieces used in 69-74. Look in your 72 AIM around UPC1, page F11...that's the page in the 70 AIM where the center support molding installation is covered. The separate roof trim piece installation is around UPC 1, page F18.Comment
