I kept seeing gear reduction starters so finally decided to buy one as I was changing transmissions and it would be a good time. The starter is configured nicely to make it easier to install on my 84 F250 with a diesel engine. The connector for the little wire is a bit strange but works nicely and the big hot wire is now pointing down so very easy to connect. If you have an old 6.9 or 7.3 diesel engine get one of these, you will be happy you did.
