tappet cover replacement

["MonteMorris" <mmorris@nemr.net>]

I have leaky side (tappet) covers on the 79B and have done what several
sites have suggested to get them to stop. I'm thinking of installing the
single replacement cover that British Automotive has on their site
(http://www.mgbmga.com/tech/mgb3.htm). Has anyone tried this? Is there
another source for this besides British Automotive since the owner is out of
the country?
Thanks,
Monte
