The Keisler ClassicFit" Kit is the most economical way to put a high strength, modern overdrive 5-speed in your Mustang. Our ClassicFit" Kits contain all the same high-quality components as our PerfectFit systems, but with an unmodified transmission. Enjoy a 5-Speed System with low RPM cruising, and great fuel economy today.

Keisler ClassicFit™ Offset Shifter is now available! It provides the same correct shift lever attachment point as our premium PerfectFit™ series, but in a lower cost "bolt on" package. Modification of the 4-speed shifter hole is required for some applications. (Note: If you desire a little-to-no mod installation, please see our PerfectFit™ series of transmission systems).
