Brake swap 77? into 69 c20

[LilTruckMan'69]

My 69 c20 has a front frame section and brake master/booster setup from a ?77? chevy 3/4t and even after looking up some stuff I decided it was time to ask for more info.

What should I do to swap out master/booster?

The bracketry off of booster to firewall appears to be different.

What should I do to swap in this portion of the disc swap??


Will the master cylinder just swap in and out and I'm done or do I need (or should I) swap out entire booster/master combo?

Anyone that has done this swap or has good info on this upper portion of the swap and could share could be a great help.

Thanks in advance.
