thanks for the info,, I am trying to change the Xmember under the bell housing,, I have front mounts,, i had gotten the cross member from tom meyers in OKlahoma but it appears he sent me the wrong one,, the inner measurement on my 53 3100 is 30.5 inches,, the xmember I got was 33 inches could be from a bigger truck,, soo Im trying to figure out what i needed to do,,,
