I pulled out the 4 speed gearbox out of the drag car today. measured it with the C6 i got & found out that the C6 was 90mm shorter than the auto fitted to the DL LTD. Has anybody fitted a C6 to a EF/EL falcon? is there a longer extension housing for a C6 availiable? The measurements were taken from the front of the bellhousing to the rear mount.
