Jack Silver bought Keisler out. It is a Keisler setup. They simply have engineered the bell, trans mount, cabling, and some additional items you need to bolt it into an A body, with lots of documentation for a pretty straight-forward install. The GM 4L65E is a 3 speed with OD with no trans tunnel cutting into passenger compartment. There is some trimming to make it fit inside of the cross-brace. It came with a controller, however the Holley Dominator EFI has provisions for this exact tranny and will control the engine and tranny combo.
