OK here goes - 89' Supra Comp Floor Resto

You can have mine jet. I'm cutting it off flush with the floor. I have to cut it because it was welded at the plate, and I want it gone. I guess you would have to cut yours and weld mine on though.

Most of the time it's aluminum to steel. The aluminum pylon will loosen out of the steel socket. Take out all set screws, spray with oil. Then take a large pipe wrench 2 footer min. 3 or 4 foot better, with a cheater bar. Fasten close to floor and break loose. Heat if necessary. Works like a charm. Don't forget to tape pylon for protection from pipe wrench jaws.

I also have one from my sunsport.
