Extension Housing 32 Spline Auto Gears Best

This is the undisputed BEST 32 spline extension housing available for the Muncie 4 speed. Reinforced everywhere for the strength that the originals just don't have. Seal and bushing is installed, it's ready to install your shift shaft ect. and place on your Muncie for that added brute strength that you need for those Big Block GM power plants of today. We offer the iron mid plate and the "Super Case" to go with this if you want to build the "Ultimate" Muncie.
