Body mount meausements

[c20pickup]

could somebody give me measurements of the three body mounts on a 70 chevy, i need the distance between the cab mount and frame mount on the back mounts, the front cab mount, and the core support to the front frame horn mount, i have new poly mounts all the way around but i believe i ave them in the wrong places because the can seems to sit forward to far, but being the fenders and bed are off the truck i have nothing to base it off of, thanks

you need to tell us if its a 10 or a 20 the mounts are different depending. On a 20 the rear mounts are about 3 and the front cab are aprox 1 1/2. Not sure but I think a 10 has 1 1/2 front and back. Not sure about the radiator support but I feel it is smaller.
