interchangeable parts of C30 trucks and G30 vans

[thugrabit]

I'm working on a 1985 Chevy G10 SWB van that I am going to convert
to a G30 eight lug suspension and I'm wondering if anyone knows what
front suspension parts are interchangeable between the Chevy C30 srw
truck and the Chevy G30 srw van. Also the front brakes interchangeable
parts.

I dont' have much knowledge on the Van's so I would rather not answer.
