I'm putting this link on so you can see post #35. Gary in Ft Worth is listed as a person that did these conversion kits utilizing the standard model A clutch housing. It's an old link but he may still be around. The supply of T170 parts and support is slowly depleting but they still show up in salvage yards and on the web sales sites on occasion.

Some folks go the Mitchell route these days even though the original designer of the synchronized transmissions and overdrives has passed. His son took up the business and still manufactures the units as far as I know. It's too bad that no one has taken up the T170 cause. It's not a bad set up although it's not a real heavy duty unit. They were made by Tremec at a factory down in Mexico.
