1970 duster slant 6 5 speed swap

If you search on there for R154, you might even find the pictures of the adapter plate I had made to mate an R154 to a slant bellhousing. Another one of those projects that didn't get far enough.

What happened to the adapter plate? Sell it? Still got it? Save the plans for it? What happened to the project? Those R154's are a pretty stout 5 speed.
