Just to put this info out there. I have a fair size machine shop with cad/cam and all the latest toys. I have made a few dozen adapter plates for MGB to Nissan trans. If you can provide a template I can fab the stuff for you for cost of materials. If you are any where near NJ we can also sit down with the bell housing and block and figure it out. I would of coarse sell the plates openly after you work the bugs out. That goes for pretty much any combination of engine trans.
