Using the Datsun 210 4 or 5 speed transmission, this kit will allow you to make a turnkey installion in your Sprite Midget or Morris Minor. (or any other in-line A-series engine powered car like the Austin A30/35 or Austin A40 Farina)

I was recently corrected regarding the legacy of the Datsun 5 speed development. Here is the information I received in a message from Terry Odenbach.
"In the 70's and early 80's I owned Bowmans Foreigh Car Repair in Redding Ca. For many of those years we were the authorized JRT service center between Sacramento and Portland We actually developed the kit and I sold several kits to Bruce when he was in Redwood City. The original kits can be identified by the Sports Conversion logo between the upper two mounting bolt holes. I sold many of these kits around the USA and other countries. I was never notified of a single problem. I still have several of the original plates plus the drill fixtures for the adapter plates and flywheels as proof"
Bruce Wyman who owned Morriservice in Redwood City later sold Morriservice to Paul Asgeirsson. Paul further improved after he took over Morriservice from Bruce and moved Morriservice north to Portland Oregon from Redwood Cty, California. Later, due to the similar drivetrain in the Sprite and Midget, it has been popularly used in those as well. The Morriservice design is considered by many ethusiasts to be a superior design over the Rivergate product and easier to install. I have made a number of subtle improvements in the current iteration that should make installation even smoother and easier. I have seen it written that the Morriservice 5 speed conversion "came later", but indeed, just the opposite is true, and was actually conceived in the late 70's
In addition, by following my recommended installation procedure, modification of the heater plenum in Spridget models is not required.
Depending on which car you are upgradiing, the kit will include some or all of the following as necessary.
The Spridget kit includes:
- Adapter Plate
- Engine to plate gasket

- modified shifter (shortened and offset) (needed for Sprite/Midget only)
- transmission case modifications (you must send me your transmission)

Transmission required is 1979-1982 Datsun 210 (not the same as B210 )
