Did gm just put the sheet metal brace in all doors, even ones without sport mirrors maybe?
My factory 81 doors have both braces you have with the same style mirrors
GM issued a service bulletin to remove and bypass those valves as they were prone to failure and didn't work properly to begin with.Some rear brake setups I've seen have a proportioning valve in the rear that will adjust based on how much the rear suspension is compressed.
I guess I've been following the TSB without even knowing it because I've always ended up removing them.GM issued a service bulletin to remove and bypass those valves as they were prone to failure and didn't work properly to begin with.
I never knew that, but I had problems with it before and I just bypassed it.GM issued a service bulletin to remove and bypass those valves as they were prone to failure and didn't work properly to begin with.
You especially want less braking in the rear of a pickup because the rear is lighter. Some rear brake setups I've seen have a proportioning valve in the rear that will adjust based on how much the rear suspension is compressed. Personally I've never messed with the prop valves in the rear disc brake swaps I've done.
I'm not sure about push rod lengths, but aren't manual brake pedals different. I thought the length of the pedal either above or below the pivot was different so there was more mechanical advantage with manual brakes.
I believe that I remember seeing that you just have to pull the rubber check valve out of the rear port. Unscrew the large nut after disconnecting the brake line.Can I just pull the guts out and use the block to hook up all the lines? I'm gonna look into that

Verify that, it's been a few years since I looked into it.
Those seat brackets are looking a bit on the flimsy side. What gauge are you using?
The factory brackets are probably similar thickness but the stamped shape makes them stronger than the flat plate you can make in a vice. I would use 11 ga if possible.
