That's true, in order for the system to work without rapid parts wear or failure, the inner primary, transmission case, clutch basket, and transmission cradle all need to be modified to a degree.
Then, the mainshaft and it's bearings, and clutch center with it's bearing, need to be fitted up.
The ring gear is aligned to the clutch basket mounted on the center, then the basket is machined and joined to the ring gear.
After that, it's all assembled together with the starter, and final adjustments are made to the modifications as required for a good final fit. The starter is tested repeatedly for proper engagement with proper clearance and interface with the rotating basket assembly.
A final adjustment on the belt tensioner is needed after the whole affair is re-installed in the chassis with the power unit (the part I have yet to do when everything gets back here from the machinist).
As it turns out, there were around 35 of these VR starter kits fitted, over a dozen of which the machinist was directly involved with, mostly with incorporating much of the above final fitment and correction under warranty. I'm at a bit of an advantage over all the VR owners, as I'm getting the total package fitted up as a complete matched assembly.
baldy, my understanding is that the QPD setup is significantly different from the Norvil setup that I'm using. Kenny switched from QPD to Norvil mid-stream, I believe (due to issues with the early ones, many of which the machinist corrected). The cradle needs cut-outs and lugs welded in place, and the Spyke starter needs an adapter plate. The transmission case needs a bit of relief at the top mounting boss, to allow for the starter body to clear. Of course, the inner primary needs a window cut out for the starter nose.
