I may have the parts you're looking for. Is it a mesh dish?

I have uploaded some pictures with measurements to my webpage: http://home.nycap.rr.com/simard/ I have to assemble to dish to get the other measurements. I should have those in a day or 2. The feedhorn ring is 6 1/2" wide The holes ( on center ) are 3/8 " in from the outer edge of the ring. This makes the distance from center of hole to oposite hole 5 3/4" The ring is 1" deep The opening of the feedhorn extends down 3/4" from the bottom of the ring. ( see pictures ) The original supports were like the one pictured. It was a round tube that was flattened on each end and had a hole drilled through it. The original tabs were about 2 or 3 inches long. The most important measurements are for the length from the dish edge to the ring edge. The original supports had a slot where the bolts attached that gave about 2 inches of "play" on both ends for fine tunning. As well, the feedhorn has allen screws that allow you to adjust the ring from flush to about 3 inches below the bottom of the outter ring for tunning. I will get the bolts needed to assemble the dish and once I have that assembled I will give you the measurements of the dish itself. Thanks a lot.
