Attached is a photo of the adapter.
The bolts in the mounting flange for the pump are horizontal.
As you can see from the photo in my previous message, the mount on the pumps I had are more diagonal,
much like the on the block side of the adapter...but a smaller/reversed pattern.
I'm sure the fellow I sold them to will let me know if they aren't what he expected and I will gladly
refund his $$$.
Thanks,
Keith
