Lightweight Suspension Options for 2nd gen Fbody?

[mikespeed95]

Hey guys,
Starting my 72 Camaro build, and pretty ignorant with domestic suspension companies, other than making my own QA1 stuff.

Does anyone make Aluminum spindles or control arms or subframes or anything for these? Or even lighter steel/chromoly?

I'm redoing the suspension anyways, so was wondering if I could shave some wieght.

Also does anyone have a budget friendly reccomendation for a rear end? I know someone is going to probably get their panties in a wad over this, but the best idea I've got so far is modify an Explorer rear end, they're cheap, strong, and have discs which saves some cash too..

Extremely open to ideas from more knowledgable people.
