I finally got these back from the guy that promised to punch
them out for me. I gave up waiting for him to punch the 1/2
inch hole so I will drill the 1/2 inch hole on my lathe. They are 
made from .125 thick 4130 plate so good for welding into your motor
mount design. The Barry 2002 series two inch diameter rubber motor 
mount is shown with a 1/2 inch bolt.

BTW I was surprised to see that Lincoln Welding recommends a non 4130 welding rod
and mild steel gussets for 4130 tube space frames. Makes sense as mild steel elongates
more and is less likely to crack.

If anybody wants these ask Tracy as I will send them to him. Best to get a few
when you order his EFI or redrive. Most designs will require a 
minimum of six. I had 86 made and will keep a few for myself.
