Thanks mello dude for the info and the compliment. I've been at building this Bandit for 19 1/2 years now - if it's not awesome to anybody else, at least it's what I want.
I found an All Balls Racing bearing kit on Amazon for $32.75 and it includes both dust seals so I'm going to go ahead and buy it. Maybe I can get around to swapping the bearings over the holidays, unless I spend the whole 2 weeks off watching TV and drinking beer!
