Fred,
Tried to e-mail you a couple of times but my server kicked it back and said it was not valid
I also turned on my e-mail option for this site.
I have had no luck locating the frame# on my car - it hads a pretty heavy coat of paint on it and i just need to look closer.
I will look into the MGB upgrade you mentioned - i have the book -should have looked. If Ron has some of the upgrades laying around, i may have to get ahold of him and see what is involved in changing-out. I really dislike the stock unit, even though it rides very nice and has none of the shake that some of the other replica owner complain about. It is the weakness and lack of adjustability that makes me crazy.
Let me know what you fine out about yours (soon to be).
If you make it out in January, you are more than welcome to check out our baby. I currently have the engine torn down to the short block - putting in some hot heads and cleaning up the compartment some.
Roy
