F150 and econoline rear

[Lost]

So anyone know differences . Spring perch width axle width etc. Found a real low mileage 1990 Econoline h9 rear cheap want to get for friend if it will work in F150 truck

Should all be the same, im lookin to get a sterlin 10.25 from a 03 e-350 for my truck, its has disk brakes, and the old 8 lug still.

I'd have to lay a tape to see if they relocated the perches, but the frame widths are different, the vans are wider.

Yea, Ive got to measure mine. I worked on a few 90's style, frame didnt seem any wider then mine. You think for cost effect, if they put the same rear in, they would just weld all mounts in the same spot lol.

I's only a few inches difference, not anything major, but just enough to ruin someone's day... I know the rear bumpers won't swap because of it. Welding the mounting pads on doesn't require much, so having a second jug isn't that big an issue. If the axle were totally different, that would be a different story. You would have to give me a few days, but I have a 79 van and the 78 truck, I can find out. I can also check on the 88 250 to compare, also have a 85 150... Don't know about the u-joints though if they are the same, would have to look that up.

Just wanted to know the perchs were different it was to cold to get my tape measure out. Ujionts r trivial to figure out but perch reweld would not be worth it for me.

Thanks for replies . Any input is welcome .

Do not go out of your way . The rear is going no where and its to cold to work outside anyway . But thanks

way back in the 70's the center was offset to one side more then the truck axles. just because the perches are the same width check from perch to pinion from both sides also so as your drive shaft dont run at a stupid angle

 

[Fellro]

Perches are set 4" wider, happened to be there and had a few minutes. (79 E150 compared to 85 F250 LD) 46" to 42" between the springs.

On the 92 F350, the whole driveline is about 4" off center to the passenger side. I discovered that when I did the Cummins conversion...
