I no longer have my links to PFF threads I saved with Axle info - I tried to bookmark them as they came up and their was a plethora of information in them (I think the error is on my end as I prolly deleted them accidentally)
1988 GT SC3800 / 4T65E-HD Swap - Donor car was a 1997 Buick Park Avenue Ultra
Anyway the factory Buick tri-pots have a grove in them (the ones in the transmission)
...On the driver side the grove is dead center over the Rear Laterial Control Arm Bolt in the Cradle
...On the passenger side the grove is about 3/4" to the left on the Rear Laterial Control Arm Bolt in the Cradle
So I'm assuming my engine / transmission is off about 3/4 inch to the Drivers Side?
I can get some pics up if needed
Any help would be well... um very helpful
