Need advice on possible trade

[BigRed]

I have '75 SWB that I am trying to trade for a '68 LWB I found. It has a 350 (I think) with a 4 speed on the floor. It seems to be in fairly decent condition. I haven't seen the truck in person (will today probably) but I've seen pictures. The guy said there is a linkage adjustment problem with the 4-speed and that it won't go in gear all the way.

I want to know from you guys (the experts) what I should look for in this truck. What are some common things with these trucks that I need to watch for? Does the 4-speed sound like problems? This will be my daily driver for at least the next year, so I need it to run consistently.

Thanks,
Scott
