The arms on all three cars are different. the c's and hubs and nuckles are allthe same. diff pullies are thr same on xxxs and jrxs, different on type r. belts are all diff. cvds might swap between xxxs and jrxs, type r is different. spurs will swap from jrxs and type r, thats all i can think of at the moment. I have/had all three cars so it is easy to compare. Need another xxxs to be comeplete.
