Thanks all - finally got it - after 3 tries. The two diamond shaped covers need a film of sealant, and one of the little bolt holes for them is NOT a blind hole. Teflon tape on the threads fixed that one. Get the boots and their seats squeaky clean, do one at a time, and let the sealant set up 24 hours before exposing to oil. I used #2 Permatex, I'm sure others would work as well.
