Motor Sport Parts

This update will allow for use of the late style 915 main shaft seal and o-ring on early transmissions ('72-'75) where the seal installs from the inside and the guide tube is not removable.
The update is a also good repair for those whom have loose, damaged or worn out guide tubes.

** This requires machining to fit

The original is machined off and a custom steel tube is fitted. It's further retained from the inside of the diff case with a high quality snap ring and sealed with the factory o-ring.
