Ekrupa,
Glad to hear you are joining the fraternity of owners. Go with the .82 overdrive. I really think you will be much happier in the long run. If you have time why don't you come to St. Louis and check out Run and Gun. The dates are October 10-13, 2007. You are welcome to participate but you probably won't be ready by then. It would give you a chance to meet some of the Cobra, GT40, Coupe, and other kit owners. Several are from your area (Steve Pass (cobra), Jim Pass (corvette), Fran Hall (RCR Mfg).
Here is our web site and be sure and check out our forum:

Congratulations again!
