Or... you can have your output stubs modified to accept the T2 100mm CV's. I just did that for a 914 box - some of the original smaller (914/T1 size) flange was machined off, new custom machined chromoly T2 size flange fitted and welded to the stub. Finished up with nice black oxide coating - awesome work!
