The '93 is a B3. Regarding the rear calipers...the B3 G60 likely has Girling calipers with a 38mm piston (good). If the '88 GLI is early, the rear calipers may be Girlings with a 36mm piston (bad). The 36mm Girlings had the handbrake cable mounted on top of the caliper (great for collecting debris and water to accelerate handbrake failure) :thumbdown
Crawl under the '88 GLI and look at the bottom of the caliper. If you see a hard brake line, the handbrake is attached on top (GLI has 36mm Girlings). If you find that the handbrake cable is attached to the bottom of the caliper, the GLI has 38mm Girlings (and you have a set of spare calipers as the B3 also has 38mm Girlings).
If the '88 GLI has the 36mm Girlings, the calipers can be swapped over, but to do it correctly, you'll need the hard lines that run between both 38mm Girlings and the flex line mounted in front of the torsion beam/axle. Not impossible to do, just more parts to move to make it work the way the factory intended. (Just went through this about a month ago swapping rear calipers and lines between an early '88 GLI and a late [CE2] '89 GLI) The '89 GLI was totaled, but has scads of new/good used parts installed within the last 24 months.
Good Luck on your project.
