Blue,
To my way of thinking the Corvette stuff is the way to go in the USA. Availability and options abound. 85-87 in the front seem to predominate. For the rear, the 88-92 with the parking brake built into the caliper is, IMHO, the only way to go. Many make uprights to fit these. Uprights for older parts are easily modified to use these as well. I purchased my uprights from DRB, aka GT40 Australia. These were designed for older rear parts and only require approx .25" x 3.5" ring to space the boss to accept newer spacer/caliper ear piece. If available, Kustom Metal uprights look nice in pictures. ERA uses these, but don't bother. Ultima cars use this set up also, I believe. =Lynn
