body mount measurement 71 blazer

[lpwcruzr]

I'm new to the Blazer builds, been building other 4x4s for years though. I bought a 71 blazer that has had several mods done already. The body mounts have been replaced with poly mounts. From the looks of it these are at least a 1" body lift. The combination of suspension lift and possible body lift is more than I need on this build. Can anyone tell me what stock height dimensions are on the original body mounts?

The height on the current mounts are 1 1/2" on radiator support and 3" in height on the rest of the body mounts. Trying to get an idea of how much body lift these are.

Thanks
