Hmm thats an interesting question. Somehow though, i don't think it will. Since the Truck is RWD, the positioning of the clutch and parts would be different. I have a feeling that the flywheel would be thicker (quite thick actually), wheras the FWD one is thin. Bolt pattern would be the same for sure. All V6 FWD flywheels are the same (from 1988 to 2001 and possible later, havn't checked). So you could use ANY of them, they all use the same bolt pattern and are all the same thickness. Also, the MR2 3SGTE (SW20) flywheel is the same bolt pattern and will fit, however is 0.5" too small and MAY slip, since the V6 has quite a bit of torque. On my conversion, I used a 1993 3VZ-FE flywheel. Bolted in and to this day is working 100%.
PS. If you need any info/pics/advice, let me know (or others of course) because I have done the swap myself and have lots of info.
