I bought a 1983 GMC Jimmy with a 6.2 Diesel.

Want to put the 6.2 in my '89 Suburban, which I succesfully "manualized" last Fall with a Getrag 5-speed from an '88 pickup..

Jimmy had A/T, so I now need a real flywheel to replace the flexplate.

Having trouble searching for a flywheel because I do not know what applications had the 6.2 with M/T.

Seems I can find manual flywheels for the 6.5.....some say it will fit, maybe? Seems '83 6.2 would be "early"..... same flywheel?

Some state a risk of breaking crank when shutting-off... Is it the single or the dual-mass FW that will do this? How can that be? Surely engine torques FW harder on startup than FW will torque engine when engine is defuelled? Surely if I suddenly take foot off accelerator to slow down, governor defuels engine and FW PLUS whole truck sends more torque through crank flange than FW alone on shutoff?

So, what year/make/model donor vehicles should I look for for the best FW for this application?

Other cautions or suggestions?

TIA for your good advice!
