Best IFS set-up for 56 Chevy Pickup front?

[andrewmp6]

The weight of that cummins i would be looking in to a new frame for it.Either one custom made or something from a 1ton pickup and put your body over it.Your looking at adding 1200lbs to your truck i won't trust the frame under it now to hold that weight.If your heart is set on keeping the stock frame its gonna take boxing it and some bracing then weld in a ifs kit and probably 4 link the rear.
