Intermediate plate for Orbitron 10 foot

[patmos]

I recently got hold of a new Orbitron 10' mesh. Some hardware are missing. The most important is the intermediate hub plate. I know it will be difficult to get here. Can somebody give the dimensions for this plate. This is what I got from the manual I've downloaded from our forum:
The intermediate plate for the 10' and 12' dish has eighteen 9/16" x 2 1/4" raised "fingers" around the edge. Position the intermediate plate with the fingers down. Each finger will then engage a rib by inserting into the square rib cavity.
I was thinking that the rib will slide between a cut slot. From the description and picture, I think it will slide into the rib( not in the mesh groove). Please help

Man...I hate to say it..but I just threw one away. Gave it to some scrap guys. Off Orbitron C10
I stored that thing for a year. and now somebody needs one.

Good Grief

Thank you guys. If I do not get one I'll try cut one from a metal sheet. I want at least the dimensions.The manual says " 9/16" x 2 1/4" fingers". If it is same dimension as top plate,then it will be easier. it also says "There is also a thinner 10 1/2" diameter silver plate"
But 10.5 in = 26.7 cm. I measured the top plate and it is 30 cm. I really cannot figure out the inner plate diameter. If it is known it would be easier to cut these fingers as said earlier
