1967 327 Engine Frame Stands/Brackets

[MickyT]

I'm trying to determine if the engine stands in our car are correct. The car was originally a 327/210hp car so they are probably correct but thought I should confirm. If I measure from the frame to the top of the stand I get 2 3/4" on pass side and 2 1/4" on drivers side. Does this sound correct? It seems odd that they are different from one side to the other.
I read David Pozzi's site and he lists different types and part numbers however I dont see any part numbers on the stands at least not on the top of them. Anybody know where they are stamped? Any help appreciated.
