The factory makes it the G50 torsion tubes in 3pieces. As long as you brace and support. You car will be fine.

Do not cut the torsion tube!

It's structural and the backbone of the car.



The best conversions I've seen have used a g50 with a shortened bell housing and input shaft. It's an expensive proposition. Personally I would keep the 4 speed. You can always change the gearing. I currently have an 88 930 4speed and an 89 930 with a g50/50.

I re-geared the 4 speed with a taller first gear and it's great. The g50 is an improvement but likely not worth the time $$'s and effort to convert.

Just my opinion
