aight thanks that clears that up.....now are all ford d44's the same. 1/2ton vs. 3/4ton? or do they have different spline counts, lengths, etc. This would be for a full width d44 by the way.
where's what one of the guys from Alloy USA emailed me....
Ford f250 3/4 ton d44 front axle:
Our kit part number is 12176. The long inner shaft is 34.75" and the short inner is 18.625". The outer shafts messure 9.72" long. All messurments are from the center of the u-joint hole to the end of the spline. The inners are 30 spline and the outer should be 19 spline.
