I have a 53' Chevy 3/4 ton that currently has a single master brake cylinder. That cylinder is shot, so I am planning on replacing it with a dual master cylinder.

I see that the normal retailers have adapter brackets like this one at Classic Parts.

Are these usable on a 3/4 ton or is it 1/2 only? Also, is buying a bracket like that one my best option, or is there a better/cheaper alternative?

Thanks!
