Just brainstorming here guys...
What about keeping the 15BF plate, both pieces of the stock aluminum bellhousing (360mm flywheel, 300mm clutch and pressure plate) and then fab an adapter to mount the h55f. That would make it a 3-piece bellhousing.
All of these provided the input shaft is long enough. This is similar to what another guy did in his 15BF swap.
