1965 k10 married sm465 np205 crossmember

[jboogee]

Sorry if I'm starting a new thread, I tried searching but could find nothing. So here is my question I have a 1965 k10 and am swapping a 70's married 465 and np205 I am using the 70's crossmember but it seems like the crossmember is tilted because the bottom flange meets where the frame angles up in the front. It seems that the crossmember should be level both top and bottom. Has anyone used this crossmember? And what modifications need to be done to have everything sit correct?
