Don't use one, You will have better luck with your stock front end.
The Mustang II spindles are short (from upper b/j to the lower b/j) so the arm tends to (at full lift) hit the upper bag mount, limiting travel to around 6". Your stock front end is good for 8" or more.
(I'm going to catch all kinds of crap for this I'm sure)
It really wouldn't be any advantage...
If you are trying to get a 5-lug ft end, IM me and I will explain how to convert.
