I just ordered and received a complete bottom end Beaton and seal kit from Boss Bearing- super nice guys to deal with. I Figured splitting the cases, might as well do it all.

Ratmuss, read this post first by b-joe before you install that kit; viewtopic.php?f=21&t=3905&p=13618&hilit=boss&sid=59d01e6026f5edef2e5edd4b9e93bd8a#p13618

I remember emailing them awhile ago although it's been deleted, anyways they couldn't tell me the manufacturers names of the parts, something like they get bearingss and seals from all over then re-assemble them as kits so any number of manufacturers could be included... didn't read well to me at the time.
