We have a 2005 Winnebago Adventurer 37G with the GM Workhorse Chassis, GM 8.1 liter and Allison 1000 combination. So far we love it. Had all 11 hydraulic cylinders rebuilt, replaced the 2 ton basement AC Heat pump and ditched the Norcold ( Nevercold) refrigerator. Currently rebuilding the Sealand/Dometic 510+ toilet. I have had difficulty sourcing the flush ball seal. E Trailer has seals for the 300 series but no listing for the 510+. Anyone have a solution? TIA.
 
Isn’t this what you need?

I don’t see the seal you are referring to. Which number is it?

So I figured it out. #4 IS the ball seal. I thought it was just the bowl to pedestal seal. The confusion stemmed from my watching seal replacement videos fot other model Dometic toilets. On those, the seal was removed from above after opening the ball.

On mine, you actually remove the bowl from the pedestal to change. A bit more of a pita but now too bad. Thanks for the answers. Back to the Road!
