Thanks, Bill-
This is about the best answer I've gotten. Actually, I failed to mention, I
was thinking more on the idea of one of the four cylinder TR series, as
opposed to a six. (Unless they were all sixes, at which point I have to go
recount plugs at the local junkyard!) Oh, and I do have a Mk2 chassis, but
without the Vitesse radiator mountings.
