My 67 needs HELP PLZ!!!!!!!!!!!!!!!!!!

[nite53]

Hey Everybody,
I’m needing some help here with my 1967 C1500. I just bought this, it’s been drove hard and put away wet if ya know what I mean!!! I want to put in a TH 350, which crossmember will I need to use?
I have a 1986 Chevy truck for parts, can I put the front axle (crossmember) in from the 86?
Will I have to use the wheel cylinders from the 86 for the rear if I do use the brakes from the 86?
Can I use the power booster, proportioning valve from the 86? In other words, use all braking components from the 86 into the 67?
Could the rear axle be swapped without modification?
Does anyone know of a good source for used body parts in the Myrtle Beach area?
Does anybody have a good used core support to sell me? A trans crossmember?
I can’t see any tag on the firewall like the cars had, where is the “body tag” that gives paint codes? There is “DD” under the VIN on the door post, is that color code? If so, what is the color?
I know, lots of questions, I just got it, I’ve built many cars over 30 years, but my first truck to build as a toy!!! Thanks in advance for all your thoughts.
