spline count

[diymirage]

hey guys 

im going to have my mechanic install a sure grip (or whatever ford called it) into my bronco but i need to know what spline count i have 

the truck is an 87 bronco, with a 351, and 8.8 with 3.55 gears (option 19 on the door tag) 

is there any way to tell if i have a 28 or 31 spline count axle? (short of ripping it apart) 

thanks guys

Yo diy,

8.8” rear ends generally have 31 spline axles by http://www.badshoeproductions.com/rear.htm

FORD 8.8-INCHThe 8.8-inch debuted in 1983 Broncos and F-150s, and is now found also in 4.0-liter Rangers and Explorers/Navajos. It is easily distinguished from a 9-inch by having a cover on the back.

Mustangs and maybe a few explores were the only ones to get the lighter splines. Bronco 8.8s always got the 31 count.

thanks guys 

im not too well versed on fords, and i would hate to buy the wrong one, that have the truck ******* for a week while i wait on the rest 

but, as long as we know for sure the bronco always got the 31 spline axles, that all i need to know
