DETAILS: Fits all 101, 105/115 engines. Machine screws instead of studs greatly facilitate engine or gearbox removal. Without the long rear block studs R & R engine can be accomplished without removing the gearbox along with it.  Without the long rear studs, gearbox R & R is no longer a struggle.  For either operation, the conversion to machine screws saves an immense amount of time and effort.   It is truly gratifying being able to unhitch the engine from the gearbox  and hoist out the engine by itself.  It is a blessing to be able to lay under the car on jack stands at the track and pull a gearbox out without the impediment of the long studs. The replacement  machine screws require a 10mm socket.

This conversion kit has four steel inserts to replace the aluminum 8mx1.25 threads in the back of the block.   The aluminum threads would strip out if used with the machine screws. This kit contains a drill for enlarging the stud hole and a tap to cut new threads to accept the steel insert.   It is then a simple matter to screw in the insert and drive in the four stakes to hold the threaded insert in place permanently. 

Kit contains:  four threaded steel inserts, drill, tap and four machine screws with washers.

Note:  101 cars must request shorter machine screws.
