64 Chevy rear
Basicly same as 55-64 ; with the auto it should be alright. Chunks , etc are easy to change like a 9 inch Ford and easy to find ; so maybe find a spare in case you do get the 400 horse hitting hard ! A 57 Pontiac will bolt in that use to be a good replacement back in the 60s and is stronger. You might also ask around to see if there are any 9 inch bolt-ins ...

Sorry ; Im wrong,I meant the pontiac will bolt in a 55-57 Chevy car and as far as the 9 inch the 64 Chevy is coil springs so I guess there wouldnt be a bolt in 9 inch but you would have to weld your parts onto your rear.
