A shot in the dark - GM rocker moulding interchange?
Permalink  

Hi there guys and gals, I was just wondering whether anyone has some old time knowledge about parts interchange in the GM world. Would anyone know if the rocker mouldings on a '57 Chev 2 door hardtop are the same as a '57 Pontiac 2 door hardtop, given that the cabin window and beltline ones are all the same on the two models.

 

I'm asking because the ones on my US built '57 Poncho Star Chief are missing, and it would be easier to source Chev ones than Pontiac, I assume. 

 

Alternatively, if somebody has some which they could measure the length and height of, it would at least give me a clue.

 

Many thanks in anticipation of any responses.

Pretty sure that's a big No. The two cars are different lengths and when you look at a US Pontiac some of the difference can easily be seen in the front fender by looking at the space between the door opening and wheel well along the rocker area. If your car was a Canadian Pontiac the answer would be likely yes.

57 Pontiac has a different kick at the bottom of the rocker. More like a 55 chev.....think this is true for US and Canadian models?

Thanks Guys for the comments. You have confirmed what I was told on the Tri-five.com site, that the '57 Chev and Pontiac have different profile rockers.

Ah well, plan B (when I formulate it).
