Ron,

Why do you want late model calipers? What is the problem?

Are your early stock calipers leaking? Are you getting brake-fade and want to upgrade the rotors from solid to vented?

Stock Jag solid rotors are 0.50 inches. The after-market vented rotors from CWI are 0.870 inches

If your old calipers leak, maybe have them sleeved or get replacements. To
upgrade to the wider caliper you will need the spacers, "bridges" to widen the caliper.

CWI did my rear and it has the "bridged" Girling calipers and the thicker, 0.870, vented rotors.

Without the rotor upgrade, I'm not clear as to the advantage in swapping early for late model calipers.

What are the disadvantages to the early units against the later model versions?

Just asking to make clear why you want to change out the early calipers, the rear ends are a lot of work to play with!
