You can install the C30 control arms onto your C10 crossmember. But if you are going to be changing engines anyway, it may be a little less work to just change the entire front suspension. Although I believe the holes in the crossmember for the motor mounts are the same.

So im going to wind up going one of two ways. Either pull the entire front suspension and rear diff from the C30 and make my truck into a C30 or pull the entire front end from the C30 and the front end of my C10 and do a full a cross member swap with the 2500LD spindles and rotors. Unless i can pull just the Upper and lower control arms from the C30 and bolt them to my C10s existing front end. But to be honest i would rather pull the entire crossmember assembly since that will also give me the proper engine mounting points for the 6.2 Diesel. Unless of course the mount points are the same between cross members.
