Well, I don't have it, but my dad does. It's obviously for a round pattern transmission, and it was marked by the seller (swap meet) as NV4500 to 205 for a Chev. However, I have an issue with that. For one, there is no hole for the shifter on the passenger side of the adapter. On the drivers side are two holes that appear to be right if the shifter was on the drivers side. One or the other looks useable. On the adapter to transmission flange, there is a cutout on what would be the passenger side of the bolt pattern, it looks as if it would be to clear something. But since the GM adapters aren't "clearanced" the same way, I'm not sure what that is for. Anyone got any ideas? I suspect some drivers side driveshaft application, but I have no experience with anything but passenger side GM stuff.
