I haven't posted anything in awhile but I need some help! I've been slowly putting a new drive train in my Chevy. Nothing fancy. Just a SBC with a Saginaw 3 speed. I thought I had the cluch mechanism all sorted out but now it's not disengaging. No matter how much force I put on the clutch fork it doesn't move. Like I said, it was working but now it isn't. The car hasn't been driven. The motor hasn't even run. Thanks for you help.
