 I agree with yelodog. If your engine is a stock 2.0L or upgraded 2.2L but still has the 907 flywheel then go to the http://www.jhps.com and check out the Supra conversion kit. It has all you need for the conversion including clutch pressure plate and driven plate etc.  You can get it yourself direct from Conversion Components in New Zealand, but Greg already has gone through this hassle for you.

The supra 5 speed gearboxes come in W55, W56, W77 and W58. You would want the W58. Its 5th gear reduces your rpm by 1000 rpm while cruising at highways!

The W58 are rare. You can get one through the JHPS. Those are thouroughly checked and with new bearings etc. But they come at a cost too.

If you want to find one yourself then check for the cars Jim mentioned (Toyota Supra non turbo mid 80'ies) but you could also check Lotus Excels or websites that sells parts for Lotus Excel. The Excel came fitted with the Supra W58 gearbox!!

This is where mine W58 comes from. (check-out LotusBits in the UK for example)

Now bear in mind that the conversion kit does NOT come with the extended gear shifter housing!! So find a W58 with the correct extended 530mm shifter housing, which is alsmost impossible by the way. If you don't find one with the correct shifter housing just call conversion components (Colin Dray) and he'll get you one in exchange for the one you have. Then also ask for 2 new gaskets as you need to open up the gearbox.

if you purchase your W58 from Greg then make sure he supplies you one with the 530mm shifter housing fitted. Then you are set.

One more thing. Most likely you need to drill new holes for the x-member to fit to the car. AND the x-member included in the Conversion Kit in my opinion is not an ideal fit. I used my OEM 4 speed x-member. Its perfect.  I didn't drill new holes, but welded a plate on the base of the OEM 4 speed x-member, fitted it to the existing 4 bolts and the W58. Not the best solution, but it works (plate was 6 cm wide, 1 cm thick and i believe 9 cm long) as the plate will bend albeit a little. Best solution is to drill new 4 holes right underneath the rubber mount.

The 530mm shifter housing is indeed somewhat short, but when you bend the gear shifter stick you will be fine. Check-out Dan on http://www.jhppg.com , he did this and has pictures for you included. I had the straight short shifter stick from the Excel and i had it altered/welded to fit the car (i could make a picture for you if you need one)

if you have any further questions don't hesitate, do ask.
