GREG JEWELL - '64 Corvette

 

Here are photos of my '64 Corvette in which I recently installed your TKO-600 5-speed transmission.  I, with the help of my brother and son-in-law, were able to install the transmission with no problems in a weekend.  Instructions were good and by taking our time we did not run into any mechanical or clearance issues.  The shifter fits so well in the existing opening, no one would ever know it was not original.  The car runs great and the fifth gear smoothes out highway speeds making the car a lot of fun to drive.  The ratio between the first four gears is perfect.  A lot of fun to drive.  Thank you for the great product.
