1972 chevy clutch problem

[JibSheet]

My 72 chevy has a sm465 w/205 t case. it has a newer crate motor put in a few years ago with less than 30k. i just bought it and the clutch never fulled disengages from the engine. to put it in gear sometimes i have to turn off the engine and put in gear, then start back up.

its a pain at stop lights because i have to pray i can get it in 2nd before i fully stopped or else i run into trouble. also shifting up is a real pain because it never fully disengages. also at lights when the clutch is too the floor, if i dont have the brake on, it will continue to move.

could it be a clutch problem or a linkage problem?

thanks in advance!
