Rotary Cutter I D this Rotary Cutter?

I can't find any identification on the gear box, and no shops around here seem to be able to match the input housing gaskets.
Anyone know where I can purchase a shim/gasket set for the input shaft housing to gear box? I replaced the seal, but the real leak was from the gaskets. The two gaskets were old and brittle, about 6" diameter, with 6-3/8" bolt holes, and .040" total thickness.

I would get some gasket material from an auto parts store with the appropriate thickness and make the gaskets. Should be fairly simple and low cost.

I tried that. The distance between the inner radius and the bolt holes is very thin, and by the time I got it to fit over the housing, the gasket tore. I might as well just slop a bunch of sealant on the old gaskets and cross my fingers.
I can't believe these are so hard to locate. Most every gear box I see has what appears to be the same gasket or shim, and on line stores don't give dimensions.
Thanks again for your suggestions.
