Cadillac 500 1979 chevy K30 1 ton 4WD

[sameoldthang]

And I have some questions. I was given a 500 from a 1973 Eldorado FWD and have a couple points I wanna hit. The truck is a 1979 chevy K30 1 ton dually
with a turbo 400, np205 and a GM10.5 14 bolt 4.56?

- Motor mounts make my own or get the frame mount and pad from a 1977-79 deville?

- BOP with the trans fit on the back of the motor being cadillac used a turbo 400 too?

- oil pan can i use the existing oil pan on the eldorado rear sump?

- torque converter use the existing flywheel on the 500 and get a converter for a eldorado?

thanks!
