Mine’s the same, stock front end with poly bushings, stroked 383, TTI headers, 5 speed. Everything fits and works. I’m not sure what you gain with an aftermarket crossmember on the street with a basically stock drivetrain. Weight would be a factor, though. Just my opinion. I’m not sure I’ll use poly bushings on my 64, I’d like to see if there is much difference with stock rubber bushings.
