I wish I could aford fab tech but I cant. You say its pretty straight forward, I thinck there is lots of little details, and would love to see how other people do it so I could benifit from there mistakes, but I cant find much on the web..
I installed a straight axle Dana 44 from a 78~79 Bronco into my 80 Bronco. Pretty straight forward if your mechanically inclined at all. This is the first one I did but next time I think I would install a Dana 60 setup from a late model F350 since most of it bolts right in, and hey its a Dana 60! I looked at what the Fabritech guys have done with there bolt on kits and it would make things a lot easier, but in my opinion its WAY to much money, especially when its in US dollars! If you want I'll see if I can find some of the web sites I found that helped me out before I did mine.
If your referring to a Dana 44 swap, I have a dropped pitman arm that is part of my 6" lift kit. With a straight axle install you will need a shorter steering arm. I used one from a mid 80s bronco2/ranger, this fits perfectly. I think its the same one the fabritech guys use, maybe not, but I've never hear of the pitman arm being to long. Maybe someone else has had a different experience.
