Hi All: I am ready to have my 300F brake booster (and maybe the "H" too) rebuilt. I am aware of Karp's and Booster Dewey, and have looked at their websites. There may be others as well. Do any of you have any experiences, either good or bad, you would like to share? You may email me privately, or on the server, as you wish. Thanks for the advice. 300ly, Gil C.
