I have the adapter plate, is that what you're looking for? The one I have is to adapt the bbf to a stock pg case. I also have the JW "The Wheel" flexplate that came with it if you don't already have one.
I need the plate that's like .040 inch thick. It goes between the block and bellhousing. It basically rest up on the dial pins and about it. Not sure what the real name of that plate is, but thats what I'm looking for. Can't find any new for sale. Lem told me they don't make these plates anymore.
