Brent-

Did you find an answer to your question yet?

Here's my best shot: Keep what you have, except for the Prop. valve. You'll need the '90-'91 valve to use the rear discs along with the '90 Master Cylinder. The front calipers should interchange, so keep your '88's unless you find cheap spares.

A couple of parts resources for disc swaps:

Hope this helps!
