My frame isn't dimpled. I tryed fitting the 70 P/S box to the GMC yesterday, and it was just a disaster. 1 bolt hole lined up, there was about an inch of clearence between the steering arm and the leaf spring, the box hit the core support mount. So, today I'm putting my manual steering box back in.
Sorry for the hijack, thats a beautiful 68 Chevy. (I can't get over how pretty it is
)
