One other thing regarding having Precision Alloy modify your output stubs. Todd does this work in batches - he'll do a batch of output stubs all at one time, with machine set-up, etc. Economy of mass production you know! So when he starts needing another batch of stubs, he'll do them - which may be in a few weeks, or may be 6-8 months. He most likely won't do a one-off set of stubs, unless you're really desperate and have the money to back up the immediate need! What he did with mine was modify/make them along with a regular batch he was doing, I think I waited 2-3 months to get them done. Just FYI.
As stated before, I'm not that familiar with the 944 CV sizes. OD sizes of the common CV's are:
T1 94mm
T2 100mm
T4 100mm
930 108mm
There are also differences in width of the joints, what size axles they take (diameter and spline count) and even attachment bolt size.
A must have source of CV and axle info is here:

Unfortunately he doesn't cover the 944 stuff, but I think some of it is similar to what he does measure (at least you can compare).
