It just needs a shim or two. Do yourself a favor and get a m2c clutch, you'll be glad ya did.
A properly shimmed stock clutch works perfectly fine. I've never had a single problem with the stock clutch in 3 LST2 trucks. I don't see the need to change the clutch, personally.
There are shims that can be bought to properly shim the clutch. You want just a teeny little bit of in and out play on the clutchbell. The last one I shimmed, I had to shim it enough so the clutchbell didnt rub on the flywheel.
