If i were to do a top swap and put an hd diff on my l36 would i be able to use a stock l67 pcm? And second would i be able to use my stock axles or would i need different ones?
 


Engine:
You want the pcm reprogrammed, a top swap is different enough from an L67 that you should.

Trans:
You might need to have the programming in the pcm changed for the gear ratio. I've seen some accept it and others don't.
You need the shorter HD passenger side axle.

If he is just putting the HD Diff on his non HD trans, It won't change his gear ratio tho. So no tuning needed.
