400ex lonestar/PEP front end and axle on 450r

[Fast350ex]

I race a 426ex with Lonestar +2 a-arms with PEP limited mass shocks and a Lonestar Axcaliber axle and I'm looking at the 450R's right now but I don't want to spend to much on aftermarket stuff for the 450. So I was wondering if my Lonestar/PEP front end and axle would fit on a 450R?

The shocks would but they would be slightly shorter eye to eye. The 450r A-arms dont work on a 400ex so im thinking the 400ex A-arms wont work on a 450r.

The axle might. Just look in a mag that sells axles and look at the parts numbers and see if the numbers are the same as the 400ex.
