Rd350 carb bowl gasket part #?

[Fffrank]

Starting to put my project back together (yayyy! Everything is clean!) and the eBay bowl gaskets that I bought didn't fit. I had assumed vm28 gaskets were all the same but these were intended for a snowmobile and not the right size (though they were a very similar shape.)

Anyone know the correct mikuni part number (or have a source for buying the gaskets without building an entire rebuild kit?)

Economy Cycle has them.
