69-70 shelby twist hood locks ?

[Kris 90]

I have a pair of hood locks I am trying to get some info on. I bought some parts today and the guy made me a good deal on them because he just wanted to get rid of the rest of the mustang stuff he had. I know the base plates and retainers are original ford parts because of the part numbers. The actual twist lock I don't think even goes with them. The base plates from what I have seen are a mach 1 style and the twist lock is for a 69-70 shelby. The twist lock does not have a ford number on it just has ACSCO prod burbank cast into the inside. I didn't know if they would have ford part numbers even if they were original since they are for a shelby. I know they are desirable parts even if they are not complete or originals as this style hood lock alone without the base sells for 79.99 new.
