Here is some info I got from Will (I think it was him) some time ago on how to possibly use factory axles and an intermediate shaft from a Beretta to move the engine/tranny combo 2" to the left:
Use a 94-96 Grand Am shaft (12 5/8") on the left and the 83 Celebrity, 83 6000, 89-91 Sunbird or 92-96 Silhouette & Transsport shaft (18 1/4") on the right with the Beretta intermediate shaft and a homemade bracket.
Now, as far as I know, this has never been tried. This information was taken directly from the axle books. If this works, please share the information with the rest of us. I would love to move mine over to gain some water pump clearance.
