Looking to replace my push button circuit breaker boots. I have one completely missing and a few that are torn. Probably going to replace all ten. Went up to the local hardware store to see If I could figure out the threads and size without any luck. I believe they are 3/8" with a 27 thread, but not 100% sure. Order some last season from Amazon and had to return them because they were wrong. I don't want to do that again. Boat is a 1993 Seafarer 228G with the original panel. Thanks
