manual 328/323 came with 38mm halfshafts. 325 came with 27mm halfshafts.

im wondering if the 328 halfshafts would be a good upgrade from the 325 ones im currently running (well kinda running i blew one up yesterday).

it broke at the joint not on the shaft so who knows if the joints are any stronger in the 328 halfshafts???

328 halfshafts should fit in 325 rear trailing arms correct?
