just wondering if i wher to swap my 91 body onto a 78 frame with the solid front axle d44 and 9'' in the rear would be easer than just swaping out the drivetrain?
yes and no becvasue when you swap bodys you gotta remove all dash plugs awires and firewall stuff and font clip withc is alot of work and the njust switcvh drive trains is about the same ones just alot eaiser casue its two moves front clip body or
swap drive train reall either or would work

i would do the sas dana 44hp from the 78 and keep the 8.8 you already have in the rear if that is what you want i know the dana 60 hp would be a better swap but if you have the 78 bronco stuff and want to use it the carrier and gears from your ttb will interchange with dana 44hp just a thought [cheers]

why would you keep the 8.8 thought the 9'' was as strong as they get ?
i am using this for just a bogger .....:rolleyes:

The 8.8 aint that bad, theres lots of guys on FSB.com that run 37s on them, and it would be alot easier to just swap the 44 under the bronco. Easiest way is to to a leaf sprung set up. And if you really want a beefy rearend go find a sterling 10.25, they're in almost every F250-350 etc...

Swap the solid axle 44 into your truck but keep it coil sprung it is real easy on those things move your radius arm brackets back use the radius arms and track bar and strg from the 78 and your coils from the 91 add the track bar bracket to the 91 frame and get rid of the ttb axle and pivot brackets under the engine crossmember.
The 9 in is not the end all of rear ends they can be built very strong (the drag racers use 9 inches because they can be built strong but are very lightwieght for their strength) but in stock form they are an average diff a little stronger than a 44 the 8.8 is apperently about as strong as the 9 in (8.8 means it has an 8.8 in ring gear the 9 in means a 9 in ring gear do the math) but the 8.8 is still a C clip rear end so if you break an axle there is nothing to keep it from sliding out although I have yet to see someone break an axle ( they are 31 spline like the heavier version of the 9 in. the 9 in. in the trucks came with a 28 or 31 spline axle)
