diesel mate ive checked the box along side a normal type 9 and when i marked the input shaft at the front and rear of the box then placed in second the normal type 9 came back to the marks but the p100 one went a quarter turn more and the only mod you will have to do to as far as i know is the input shaft is alot longer than the normal type 9 so it will need some taking off if your going to put it up to a pinto. just to let you know the differance between the 2 boxs are as follows below.

type 9 ratios p100 ratios
1st 3.65 1st 3.91
2nd 1.97 2nd 2.29
3rd 1.37 3rd 1.38
4th 1.37 4th 1.38
5th 0.82 5th 0.82
