i am concerned about what vehicle it was coming out of, but it's not too much trouble to get it under your ranger. would most likely take a friend, and some welding, but it's a day or two to get it under.
not sure on the price to get it under there though, as alot can go wrong.....
it looks like a Y steeering linkage not from a ranger, which is.....a nightmare really.
If your not doing any offroading, then you may wanna keep what you have in the front but grab it and resell it! you could easily double or even triple your money if you cleaned it up a bit (looks a little rough!)
this really depends on how much money your looking to throw at it. for the price you may wanna pick it up to have and work on, and start saving for the other parts....
crossover steering linkage, trackbar and mounts, possibly new coils (depending on what vehickle this came out of), a regear, and possibly a locker. there are a few good posts in the tech section on what you may need to get or do for it to go under your ranger.
