I think I already know the answer to this and why I didn't do it in the first place is a mystery...
I have the T-5 installed (again) but the clutch disc will not completely disengage from the flywheel. With the back wheels off the ground, the truck in gear, and the clutch pedal pressed in (adjusted to where there is no play in the pedal at all) the tires spin and if you push in the brake it will kill the motor. Is this the drag several of you have mentioned? Do I need to lengthen the splines on the mainshaft? I can see that the pressure plate and clutch move... I can fit the very tip of a flat screwdriver inbetween the clutch and the flywheel when the clutch pedal is pushed in.
Starting to get frustrated and really want to have the truck going by the end of next week.
