what would you redo? id love to know... this is my truck and im not ever gettin rid of it and im tryin to fix whats not right.
the first time i drove a ranger i was 9. it was my grandpas white stick shift (like mine) and after he died that year, i have wanted one since then. so im gonna fix and keep this one
i'd cut the whole cab cage out. if it's tweaker build, it's most likely crappy tube and horrible welds. also, it is not tucked tight to the cab at all, in the third pic it looks like i could fit my fist through the gap between the cab and the tube on the A pillar. i would also rip out the dash, because from the looks of it the stock gauge cluster is just sitting on the floor. also based on your kill switch thread, and the spiderweb of wires by the steering wheel in the 1st picture, there is most likely a lot of stuff that needs to be re-done to make it safer.
i would really like a picture of the beams, i highly doubt that they're f150 beams because they need way too much work to make them work on a ranger with the two sides equally spaced out from stock. after that i would put a real shock in the front, get rid of the tundra coils (which they're not, tundras use a strut and that is WAY too long and wide to fit on there) because they're bent... probably from the tweaker work on the front lift. also, move your brake line ASAP! it can get pinched between the spring and then you'll have no brakes, talk about a liability. since you're doing all this work to the front end, i would definitely make a new bumper that has some nice welds, a functional skid plate, and tubes that are bent/notched instead of just bent and doubled on top of each other.
for the bed cage, cut it off when the cab cage comes out as well. once the bed cage is out, remove the rest of the bed. there is honestly no reason to keep it on there since the majority of it is cut out. it is possible to pull the stock metal bedsides off and mount them to a bedcage, or you could just get fiberglass and mount that up. since you're replacing the front shocks, get some for the rear end at the same time. a 2.0x14 or 16" with a reservoir would be perfect for your truck, and if you can afford a 2.5 body that would be even better. rebuild the cage with some nice tube, lay out the tubes better so that it doesnt look like the back half of the cage was added on as an after thought. double shear your shock mounts, and mount it off the axle or the spring plates with some nice quality tabs. how you mount your spare is up to you, but the only thing i can imagine if i were to hit the back bumper with my truck is that i'd annihilate the ratchet for the strap, and then your spare would bounce out and we'd both be in trouble.
