I am trying to replace a broken American Standard wall hung toilet from 1959. I purchased a Gerber maxell wall hung toilet (model 20-021) to replace it. The hole pattern appears to be the same between American Standard and Gerber. But the thing that is causing me issues is that the coupling coming out of the wall comes 5/8" out of the wall. The groove that it is supposed to fit into on the Maxwell toilet is 1/2" deep. So already there is 1/8" collision there. But there's supposed to be a neoprene gasket in between them. According to Zurn it should compress from 3/4" down to 1/2". So by my math you would want the coupling coming out of the wall to *not* come out of the wall, but instead be flush with the wall.
So - I see a couple options:
1. get a pile of washers and space toilet away from wall by 5/8".
2. Use a dremel with a cutoff wheel and cut off 5/8" of the coupling sticking out of the wall. I'm worried that the remaining pipe might be too thin and would slice right through the neoprene gasket.
3. Cut a sheet of 5/8" plywood to match the shape of the back of the toilet bowl, then cut holes in that and mount that to wall (ugliest route, but stronger than #2)
I noticed that the coupling sticking out of the wall is threaded. So in theory I could just tighten the threads more and screw it 5/8" more into the wall - but I think the threads are rusted to all hell (being that they've been exposed to toilet water for the last 60 years) so I don't see that moving. Also I don't have a pipe wrench even close to big enough to fit around that coupling... I've included pictures below showing my predicament.
Any ideas?
