Manual tranny question

92 1500 Silverado 2WD. Shifts into gear but when clutch released it's almost like it's still in neutral - barely moves like no power transfer to tranny. I suspect clutch may be shot -- anybody have a take? I believe transmission/clutch is still original.

ANy advice greatly appreciated. Thanks in advance.

Sounds like clutch or pressure plate. Time to pull the tranny!
