What exactly is required to lay frame on 20's and 22's

[needforspeed502]

Hey guys after ready a bunch of stuff on the forums about the porterbuilt dropmember and some options for the rear i still have a few questions.

First off, for the front suspension, with the porterbuilt dropmember are drop spindles still recommended? Also since the porterbuilt website is down, what all steering components are required, and is it simple to hook the new r&p up to any power steering pump(ie 5.3 ls motor)? One last front suspension question, which tubular a-arms work the best to help alleviate ball joint issues, or do they all do the same thing? Also i saw 3" drop a-arms???? from DJM i think, whats the deal with those? Oh yah this is all for 20" rims

Ok on the rear suspension, what is required to lay frame on 22's? Can the stock trailing arms do it with the ece trailing arm crossmember with a c-notch? Also how big of a c-notch? And on the kp 6 link kit, will that work on a 72 2wd blazer or no? Only says 73-. Any other options for the rear that i left out please fill me in on.

Thanks guys for whatever you can offer
