I want to fit a g50/52 into a `88 carrera with 3L turbo.  As you can see in the last picture below it has longer differential House and of course the longer front mount. I have measured diff House to be approx 2.3cm longer
1. If I shorten the clutch House so it will fit 930 clutch. How much will this shorten  the tranny? How much shorter is a 930 clutch.  
2. I have seen the front mount be cut of so it become same length as short g50. How is the front modified so the early gearbox mounting will bolt on??
