Yes. It’s a drop in swap.Will it fit a GT?
@Dana Pants
I can always replace the grease and put a new clamp on it.I would be careful about buying a used or take-off GT350 half shaft.

@K4fxd are you getting into drag racing? What was the cause of your broken axle and what will you be switching to in February?I can always replace the grease and put a new clamp on it.
Honestly it only needs to last till Feb or so when I will get some real axles.
The stock GT axles are hollow.
Are the 350 axles also hollow?
