I think SVT junked it out. The drivetrain was bought by a retiring SVT employee who moved to Mesa AZ and was going to put it all (engine, transaxle and subframe) in a dune buggy. Untill he found out how heavy it would end up being. Sold them to another guy in Mesa who also wanted to put just the engine in the back of his little VW powered rail, until HE found out how heavy just the engine was.
I bought the whole shebang and sold the transaxle to a guy from Rochester NY who vacations with his SHO here in Carefree AZ. Nic97 (of SHO in a Fox Body fame) put it in for him. I still have the engine with the modified PS resevoir mounting bracket and throttle cable mounting bracket. If you get so far as to have the engine sitting in the engine compartment, let me know and I'll give you the two brackets.
