OK - I re-did my drawing to now show the set-up if I use the standard length input shaft, and a spacer. This would keep my shifter in the stock location. However, this shaft is a bit too long, or the adapter plate a bit too thin to make it work. So, where can I get an adapter plate that is thicker than the 5/8" one I have? Or should I have the input shaft machined to be shorter?
Jimi or anyone else, I did a quick web search but didn't land on any adapter plates that seem to fit the bill. Any suggestions on where I can get one that fits this application?
