What length will the prop shaft be on a car fitted with a type 9 gearbox fitted in the normal position?

I am thinking of ordering a new one rather than get a modified one (unbalanced?) from MK, and as there appears to be some horror stories regarding delays in getting props made I thought I would order one at the same time as my kit.

best to get engine in and measure from there

I would definately recommend fitting engine first as the accumulated tolerances between engine and diff can be quite large.
