Ken, the flywheel sounds OK. Probably 11" or 12" clutch. 11" is OK for your use. I didn't know the Tremec was identified by 3550. New Venture makes an all AL 5 speed OD trans. with integral bellhousing that should work for your truck and gearing(3550 and 3500.) I don't know about prices, but they are in GM since '92 or so, so should be plentiful.
Be sure to get one with the old fashioned throwout bearing and front retainer. Some may have integral throwout(hydraulic) bearing which you probably don't want. They come for both 4WD and 2WD positions. You will have to use the transmission mount for the rear since the integral bellhousing has no side mounts. Write with more questions.
