i am rebuilding a 64 bonnie and i would like to know what options i have for upgrading the front brakes to disc. Is there anything that will bolt up or do i need to modifiy to get this upgrade?? for any info yall might have.

That'* something looking into car catalogs for. Like a jegs, year one, ect. Look for any sites dealing with that gen. most of the time some place even small might have a mod

will i was wanting to know of another car i could take them off of dont really want to go brand new i have been lookin around i think 70 model chevy caprice would work but not sure thats what i am asking

Most of the cars on the forum are 80'*+

I'd suggest checking Jegs/Summit online. They tend to have some great available parts. And or..maybe it'll give you an idea what they come from to source your own.
