New to posting

Hello all,
First time posting on here, long time follower, username is, berniekal I am located in Michigan.
I have a 1967 Barracuda fastback 318 (original was 273) 4 speed.
The reason for posting is I am looking to update the rear brakes.
The car has a 7.25 rear end with 9 inch shoes, they do work but parking brake hardware is missing. 1) looking for parts to repair what I have. 2) looking to update to 10 inch with all hardware. 3) will consider updating to 8.25 or 8.75 rear complete assembly.
Right now this car is a driver and a work in progress.
Any help with steering me in the right direction to locate parts would be greatly appreciated.
Thank you, berniekal
