Default Engine mount tube size?

I'm at the office and need to order a bunch of parts, among them a bunch of the cushioned clamps to mount stuff to the engine-mount tubes, and I don't know what size those tubes are to order the correct ones.

Anybody have that handy? I'm using the IO360 7/7A dynofocal engine mount.

You need MS21919 -14 (7/8") and -12 (3/4") clamps. If your installation is anything like mine, you'll need a lot of -12 clamps.

There are a couple of diameter tubes used in the engine mount. One size is 3/4" and I know I used a large number of WDG12 clamps. I don't recall the size of the larger tubes.

My 7 engine mount has 3 tube sizes, 3/4" on the majority of the tubes, 7/8" on the circular engine mount, and 1" between the two gear legs.
