Needs some Info on Rear brakes

[Lowl!f3]

I'm calling on the brain trust of 47 to present to help me out here.

I'm using my original 1965 rear end on my truck. it has been converted over to 5 lug by swapping out the axles. I bought this kit from CCP. And it comes with the 74 drums.

My question for the trust is... Since the 74 drums work. Can I use the complete 74 brake assembly parts? All springs, wheel cylinders and shoes? Or do I have to go with the 65 parts kits and shoes?

I need to make an order. And do not want the wrong parts.


Thank you in advance
