Ok I have seen the multiple threads on the pros/cons on it and see Speartech now has a kit. Simple question.
I can see the 6 speed is bigger around than the 4 speed. Has anyone measured and documented the various circumference differences between these 2 trannies?
IE clearing various floorpans...specifically the TBSS! ![Grin](https://ls1tech.com/forums/images/smilies/LS1Tech/gr_grin.gif)
I see there is a length difference of 35mm in the two 6L's, but what's the length difference between the 6 speed and 4 speed?
