hello after tear down of the differential of my GT I need a new ring and pinion, the post on rebuild on here from last week lists splendid with a gear set but cannot find it on their site and he said 850.00 which i am sure are euro. scouring the forum i keep finding the debate of crush sleeve and Isuzu bearings will fit but the Isuzu crush sleeve only works with the Isuzu pinion and talk about a 3mm spacer. Can someone please tell me what Isuzu ring and pinion can replace the original GT and what modifications need to be done? it is a late style axle with no clips and the car was supposedly originally an automatic so not sure of the ratio. quite honestly i was so PO'ed i just kicked it into the shop corner and walked away. I have a 73 in the yard but am trying not to waste the time of swapping them to hear the firetruck behind me with that one also.
