The only real choices for a stocker that exist today are jericos and Gforce. I know of a guy that has a really good deal on a DR-4 Jerico with Long Shifter. It is the one that is close to the same length as a stock trans. It was in a stocker with a small block.I use the longer one so I don't want to carry 2 lengths of driveshafts with me for a spare. It is a good deal. e mail me if you are interested and I will send you the contact info.
