well to keep this short, i had a 2002 wrx. it was totaled and i have an 04 STI shell. im going to swap the motor, trans, diffs, axles etc. basically everything besides the suspension. (the previous motor was swapped and built) anyways, i know the r160 axles wont fit in the 04 sti hubs....so my question is, should i install my 02 wrx hubs, on the sti or is there a conversion i can do? like just take the r180 cv joints and put them on the r160 axle.... any help would be awesome! thanks im trying to void purchasing new diffs, axles, and anything else since i already have/had a working vehicle.
