Jaguar rear axle question.

I have been told there is two (at least) different producers of Jaguar brakes. Is one of them better than the other?
Is it possible to switch from Girling to Dunlop calipers or vice versa without changing anything else?

My axle is an E-type2 axle and I must have new calipers on it.


Grateful for answers!

These guys know a lot about Jag rears, unfortunately it doesn't look like they have an email contact.
