C-4 Solid Motor Mounts
They look pretty easy to make:
A couple of 2.5 x 2.5 pieces of .185 plate with a hole in it.
Tack a M12-1.75 X 35 bolt in the hole. That's the base.
Then weld a 3.75" long piece of 1.5" to 2.0" square or round tube to the plate. That's the upright tube.
Next, drill a 3/4" hole in the upright tube 3.1" from the bottom of the plate and weld in a 3.4" long piece of 3/4" thick wall tube. Make sure it's parallel to the base. That's the cross tube, it'll need to have a 1/2" ID. It is not centered in the upright. 1.5" goes to one side while 1.9 goes to the other.
You'll want to cut a small notch in the long arm of the cross tube, just look at the rubber mount that came out to see where it aligns the mount to the bracket on the engine.
Your local circle track builder should have everything in stock and the tools and knowledge to do it. Their normal roll bar tubing will work for the upright piece and the 3/4" cold rolled tube they use on steering shafts is the cat's meow for the cross tube.
I find it hard to believe someone isn't making them available for sale.
After we try these out, I'll post a picture.
