Its difficult to say the condition of the tranny, for $150 that is a good price. look for excessive leaks on the front seal / shaft area and rear seal, and try to at least spin the shaft for easy movement. Get a shifter and off you go. Depending on the flywheel you will be using, you will have to shim the starter if using a TT flywheel. You can use your 2+2 NA drive shaft. check your center bearing on your drive shaft and the transmission mount, I would replace them if I were you. Or get a single piece drive shaft. It all comes down to economics. Good luck.
