Is that frame steel or aluminum? If steel, why not weld up a set of mounts. They'd be smaller and simpler to fabricate and stronger than something clamped on.
Those mounts you show are nice but a little over-engineered and bulky. A nice simple welded mount would look and work better. In my humble opinion.

The frame is steel and I like that original paint color so much, I decided to preserve it. Welded on or otherwise brackets of steel would have ruined it. Look better and work better? I think not as these are stronger than any welds added to a frame. And the price was right....FREE! If you'll notice not only do they clamp the engine mounting plate to the frame, they also hold the jack shaft mounting plate as well.......dual purpose clamps at that.
Look better.....really?
Just my humble opinon.
Those are some pretty clamps.
Looks like they maybe made by AFT Fasteners that make mil spec clamps. The first picture, you can see AFT engraved into the clamp on the left.

If you look at these pics, you'll think otherwise.......FORE, AFT, PORT.....etc.
They were made by a company called Ashtech and I believe they were part of GPS tracking devices of some type. I think one landed in my friends backyard as this is how I obtained them......6 clamps all told.
I really like them, wish I could find some more.....
