Jim, what you could do if you keep having problems with it is cut the flange off the back of the cat conv where the pipe to the muffler bolts to & use one of the repair flanges like I used on my Ranger when I replaced the exhaust system this past year because someone cut the old flange off & that was the only way I could repair it. The part # for the repair flange is 41723 & it is made by Walker, & you can get it on Amazon or through Advance Auto Parts, but I am sure any parts store can get it. https://shop.advanceautoparts.com/p/walker-adapter-41723/10082242-P
If you look at the link I posted the repair flange has bubble type flare on the end of the repair flange taking the place of the doughnut gasket, then the pipe that goes to the muffler just bolts to the repair flange without any gasket & it is a leak free seal. It was a near perfect fit to the cat conv pipe & just for peace of mind I put a muffler clamp on it where it slipped over the cat conv pipe which is not there in the pic because when I took the pic I was not finished yet. That would eliminate the problem of the doughnut going bad & not being able to find the right one. Here is a pic of the repair flange on my 2000 4.0 Ranger.
