Disc Brake Conversion

[Steeveedee]

I'm trying to use the link for brakes, but it doesn't work. I get this message below. And I can't paste the screenshot into the contact field information.

Anyway. I'm looking to upgrade my '70 C20 Chevy (8 lugs) to disc brakes. I don't see anything at Summit except 6 lug stuff. I know what I need, just need to know where to get it. I think maybe the least expensive would be to dogrob the parts from a truck that will fit mine- what years, I don't know. I also don't know if they will work with 16.5" steel wheels, but I think they should. If I still worked as a mechanic, I'd know this information cold, but I left that occupation as a living in 1984 when I went to work as an engineer.

Any pointers?

Thanks in advance.
