the truck flywheel are wider aren't they?

No. In D100/150 applications it's the same starter, same clutch, same throwout bearing and same transmission from about 1976-87.

Truck are 11 inch. Heavier for off idle torque during towing and hauling.

D100/150 are 10.95", which use a 130-tooth flywheel (same as '70-'74 B/RB and '70-'71 Hemi).

i thought so my clutch wouldn't fit on the truck one I tried

Which exact model/configuration truck did you have? There are several truck flywheels, including 2WD and 4WD, with 10.5", 10.95", 11", 12", and 14" clutches.

The flywheel on RockAuto is a car flywheel that also happens to fit mid-'70s to late 1980s D100/!50 models.
