well, according to this recipt the part was $818.20 (im not sure if thats including labour or not)
Thats whats getting me scotty, the price of this thing....
The link to the tranny mount you posted was the first thing i thought of, but ive since got a price on that part (just to figure out) and it's significantly cheaper than $818.20.
maybe the last owner that had this work done got very ripped off. I dunno.
