Disc Brake Upgrade Reference Thread

***************THIS CONVERSION IS NO LONGER RECOMMENDED UNTIL THE ALIGNMENT ISSUE CAN BE RESOLVED***************

OK I finally got around to compiling this.
Here is a list of parts and part numbers for converting to 6 lug disc brakes using factory parts. There will likely be updates later to the applications and years, as this here is just what I can confirm at this time.

You will need the following parts from a '88-'98 C1500 or 7200#GVW C2500 pickup or Suburban, or from a Express or Savanah Van thru 2002 in a 1500 or 7200#GVW 2500 model.

Spindles (unless you want dropped spindles)
Rotors (if you find a 7200# GVW 2500 series)
Calipers
Front caliper hoses
Outer tie rods
Tie rod adjusting sleeve
Lower control arm from a C20 (the '67-'72 have shorter bumpstop brackets. The '73-'87's will work, but may need to modify bumpstop bracket depending on rideheight)

Don't forget all the little parts like, spindle nuts and washers, dust caps, nuts, bolts, washers, etc.

The following are part numbers for new or rebuilt parts that can be sourced from your local auto parts store. Some of these are duplicates of the above in case you need new parts instead of good used ones. These part numbers I found online at CSK/O'Reilleys website. I looked these parts up for a '90 C2500 7200#GVW pickup.
