hey i was wondering if you could swap in the axle from gsl se into an rx3.
brakes diff everything. thanks.

 

It's possible, but not easy. The SE rear will be around 4-5 inches wider, and you'd need to fabricate all new suspension mounts, plus get the driveshaft to accept the SE diff. Most people would go to a Ford or Hilux rear if you're going to go through all that trouble. I'm not sure what you're planning to use this car for though.
