A body 3in inboard spring kit

Does anybody have specs or pic so I can make my own boxes? I heard the mopar ones are real thin.

I've installed them on several cars with no problem. The stock frame rails are even thinner than the M/P box kit. But if you must make your own ,just measure your front spring bushing and make it 1/16 to 1/8 inch bigger, and it will be fine

when we relocated mine we took the frt hanger and welded it inside the new m/p box,made it extra strong.been in there since 1990 with no wear/problem.

We used the kit. Very simple. The frame material is thinner. We ended up re-inforcing there..... For extra strength. Likely not necessary.
