?'s for you three on the tree gurus

[blazerparts]

The local Salvation Army has a '69 GMC 3/4 ton they took in as a donation for sale. It's a 292 three on the tree. Engine seems to run good (looks like the carb has been rebuilt, new dist. cap and plug wires, plugs). Body has a few dings but no rust. A sticker on the tailgate identifies it was an airport vehicle in the bay area at one time. They drop the price $50 a week until it sells, currently it's at $700. I looked at it and started it up but I noticed two things: first the transmission lever seems to be stuck in a forward gear and second the clutch doesn't disengage until almost fully let out. I haven't had a manuel transmission vehicle lately but if I remember correctly when the clutch doesn't let out until the pedal is almost out of travel there is too much clutch.

My questions:
- am I correct in thinking that when the clutch doesn't disengage until the pedal is almost fully let out, there is too much clutch and the linkage needs to be loosened?

- is there a common problem with the shift linkage in this type of truck and how do I fix?

Thanks in advance to your responses.
