4 speed swap parts

[dragonball98312]

Hey there everyone. Ive been slowly gathering parts to convert my k5 over from an automatic. Havent had alot of luck finding the conversion parts needed locally. I did find a 73 c10 with a 3 on the tree. A few possible issues tho. Its a 6 cylinder and I have a v8. Also its got manual brakes and I have vacuum. Im pretty sure the v8 zbar is different? Anyone confirm that? Also does anyone know if the pedals from a manual brake truck can be swapped with a power brake truck? Thanks guys
