Maybe folks who have done this will appear and chime in....but, you could slice both and mill so that both slices are flat; any place the thickness is equal. Mount dial indicator to crankshaft, mount alpine bell-slice to engine, Volvo bell slice to Alpine slice loosely with clamps and indicate center bearing bore of Volvo bell slice to zero run-out by tapping back and forth. Drill and pin slices to fix position, and instruct itinerant weldor to join them. After you have done this job a dozen times, it will be simple......
Some wild thoughts have passed through my mind, but were quickly discarded. For openers, the input shaft is about 3/4" SHORTER than the Alpine bell. That pretty much eliminates mating the Volvo bell to the Alpine engine. Also makes making a special plate to go between the trans and Alpine bell. The only viable method would be to graft the small end of the Volo bell to the Alpine bell, which could be shortened enough to compensate for the shorter input shaft. I can shorten then, no problem. Whack them off on the bandsaw and clean them up on the mill. How to properly align them for welding, well I don't have a clue where to start on that problem. Maybe make a plate to bolt onto the engine end of the Alpine bell. The plate would engage the pilot bearing. Set the Alpine bell on the Volvo trans, positioning it to align the Volvo pilot with the Alpine pilot bearing, then weld. Much easier said than done. The Volvo trans weighs nearly a hundred pounds. Oh yes, I can't weld worth a crap, not to mention welding Aluminum. May have to make a plate to set between the two halves in order to mate widely differing shapes. I'm pretty sure that all of that could be done, not at all sure I could. Especially the welding part. Maybe if an itinerant welder happened to appear.
