E-Brake help please

I have pulled the 7 1/4 rear end and replaced it with an 8 1/4, I have everything I need for brakes (all new) but the E-Brake hardware, my question is will all the hardware for the E-Brake that is on my 7 1/4 work in my 8 1/4 ?
Not really sure. If it helps, the '69 parts book lists the part numbers by brake diameter, not by brake width or differential size. They have different part numbers between 9", 10", and 11" applications.
