Thread: Bronco II Rear verses 65 Ranchero Rear

Tweet

Randy i`ll see what I can find, I had dug up this info on `09 the ranger was a good choice because of width (58 inches ), and most all were 5 lug with gears, but the jeepers and rock crawlers and mustang owners picked them over for the axles, other than that next inline was the mustang / or t-bird turbo coupe width wise. They are relatively strong, just not as strong as the true 9-inch. The 4x4 housing is narrower than the standard pickup housing from what I`m told.....

Another option to consider is the 8 3/4 mopar, espescially from an A-body, although you`ll have to change out the axles because most were 4 inch pattern.
A-body 66-72 -------------------------- 57 1/8"
B-Body 62-63 -------------------------- 58 1/2"
64-67(except 64 Max Wedge) - 59 1/2"
68-70 -------------------------- 60 1/8"

the best third member to get is 489 housing next being the 721, both came in suregrip or the cone style ( not as good ) ratios from 271 to 430 in street form.
