Well... purchased, installed, but I'm still working on the build and haven't gotten a chance to use it yet.
I've done a few pictures of the install in my build thread. 1957 Chevy truck re rebuild. ( Yes Ogre, I need to put it in my signature

)
We have one other who has it installed on one of his vehicles, I believe he will be getting one for his 57 Truck.
Next up will be the Gear vendors vs an over drive transmission, personal preference and cost will also need to be considered.
