I ordered a clutch kit for my 55 crown Victoria. It said it was for a 55 ford car. When it arrived it was an eleven inch clutch and pressure plate with a fine spline clutch disc. My car has a 10” course spline disc. Was this clutch for a thunder bird? Had to send it back or figure out a different flywheel.  After putting everything together my clutch grinds when on the floor and the transmission won’t go into gear   I’m thinking bad pressure plate
