Nothing new to add, but since crowd sourcing answers is more reliable when you have more of them, I figure it’s worth it.

As everyone before this said, it isn’t a perfect compatibility, so you can’t just grab any random kit and be certain it’ll be 100% right. But, there’s a decent chance it will be, or that you can improvise things enough to get it to work long enough to get the exact right bits.

Biggest problem I’ve run into over the years is flappers not making a good seal, and the pipe not fitting well. The flapper is harder to deal with, but the pipe can usually be made to work with a gasket cut to size, long enough to get a better one at convenience rather than having to run right back out.
