Default RE: actual Size of JETT/Nelson mounts

For what it's worth - just measured a couple of Jett BSE Q500 square mounts - 2.253 x 2.253 for one, and another was 2.251 x 2.249. That one had marks on it (bought the engine used) like it had been sanded just a bit on the sides.

Also, the rules state the firewall has to be 2.25" square minimum - not the mount. I'd just make sure your fuse comes out of the mold at least 2.25" square at the front end.
