Greetings all -- I have a MGA Deluxe that I am currently restoring and will be shifting my attention to the brakes in the very near future. The current set up is 1 1/2 inch Dunlop calipers on the rear and 2 1/8 inch Dunlop fronts. My question is can I use Jag Series I E-type calipers as replacements? The only difference to me appears that the Jag E-type used 1 5/8 on the rear. Thanks for your help.
