I would imagine you can jack up one side at a time and change them. there are plenty of body lift threads for rangers- basically the same deal.
Getting the bolts off were not tuff. removing the mounts from the chassis was very difficult. There are two pieces of metal, one on each side of the frame. They are like two funnels set inside of each other. I could not get them separated. And I tried very hard. I finally had to cut them apart.
keep in mind I had the engine, exhaust, steering, etc removed so everything was easily accessible. Two of them are in the cab, two of them are under the hood. You can see the two holes in the last pics I posted. Its the tall hole just to the left of the engine. In the second pic you can see the red urethane mount. Its not bolted in yet.
engine is in and it cranks and drives. most of the electrical is done. its missing one fender, a full exhaust, and the two doors need painting on the outside. I had to park it to the side for a while. I hope to get back on it soon.
the main issue now is the front springs. no way to get it aligned as it sits. I had ordered new springs and threw the old ones out(stupidly). It turned out the front springs are very different than normal. I've tried two different sets but neither work. It sits about 4" too low.
I have two more options. 1 is a junk yard. second is trying bronco springs. Based on pics in LMC, the bronco springs mount the same. I just hope they are tall enough.
I would try getting the F350 1 Ton-er springs. Buddy of mine put F250 coils on his F150 and it leveled it out.
Nice truck, I'm a sucker for these old Fords since my first project and truck was a 1979 F100 Custom Explorer with a 302, C6, and a 9 inch with posi. Bought it for $100 when I was 14. Got rid of it a year later for $200.
