Silver,
The knob replacement is pretty easy. The big question is which knob you are going to go with... some have plastic inserts, others brass, etc. to match the threads/size of the stock shifter. There's a TECH section on the "other" forum (Corvette Forum) that has pictures. (recommended) Essentially you pry off the plastic insert on top of the shifter with a flat blade screwdriver. Then you will see a nice, shiney square retainer (thanks Chevy! A locknut would have been easier!). You will need something like vice grips to allow you to lock on to the retainer. Then use a larger screwdriver as a lever under the vise grip handles and a block of wood or something flat and solid on the back side of the shifter knob top. It's very hard to get it out! (it comes straight up) If you can't budge it, try some lube like WD40, etc. I just hung on to all the tools with one hand (so they wouldn't get launced when it popped loose) and put the arm to it. Once that retainer was out, the knob unscrews. The replacements vary for the install, and normally come with instructions....
Good luck!
