I was just wondering if anyone knows wat size the front diff is in my truck its a 1989 f150 4x4 5 speed with a 5.0. The front end is i beam with the diff bolted into it and i need it rebuilt but i dont know wat size it is. Also i was wondering if there was a bolt in replacement to convert it from i beams to straight axle and if so any info would be appreciated. And my truck is at home 5 states away while im stationed in VA so i cant go outside to check the tags.
