Forgwt the 88-98 conversion for 6-lug,
You guys need to read and search this forum.
We have two members that have confirmed this conversion causes excessive positive camber.
The cure one member used for this problem was to remove the lower a-arm saddles and redrill the frame holes farther out.

Also forget using used parts.
The 71-72 and 73-87 parts are wore out junk and can only be used for core charges.
This is 2014.
I was doing those swaps back in the early 1980's.

Buy conversion spindles'
$229 most everywhere for standard height or 2.5" drop,
CPP has 6-lug rotors that work on all conversion spindles, all 71-72 and 73-87 HD spindles.
Look for summit racing to supply and ship these rotors fast.

There is tons of info on here.
