Deleted. Answered my own question

If it was a distributor question, and you didn't find this already, it's the best article to I.D. the various distributors found on these cars: http://www.mg-tabc.org/library/distributor.htm

Steve,

Many thanks for posting that link.
I was not aware of it & it is extremely useful in sorting out the dizzy on my TA.
