i think the fab 9" is stronger than the ford housing, plus it's easier to brace on the inside since they do the bracing before it's welded together. A.R.T., Art Morrison, S&W all make good kits. i guess it would depend on what area of the US you live in because shipping is killer today. It cost me $470.00 to get my chassis and fab rearend shipped from Fl to La. and that was 1 1/2 yrs. ago.
