Hello,
Do you have a black gt350? If so, we met about 9-10 yrs ago in Washington at a car show. I have #1761. No shock tower washers. Do not believe it ever did. We discussed this at the show. I was there w/ a Shelby owner, Bob Laughlin(from Tacoma). Our serial #'s are very close. Mine is Ivy green.
