You don't tell us what your plans are for either of these jeeps but unless you are a mechanic with all necessary tools and just need the jeeps for parts I would leave both of these alone. On number 2 the PO certainly didn't know (or maybe didn't care) what he was doing and that the 2.5 liter does not need to be mated with 35" tires. Not too good for the tranny either. 217k miles. Rust hole near a shackle mount that could point to unseen "rust holes" all over the frame. Shakes "bad" about 40MPH.
First one says it all with "project needs a lot". They always need more, sometimes much more, than thought at the time of purchase.
But again... what are you planning to do with it? If your goal is to make a reliable jeep out of it, I would save up some money and buy a solid, well running, no problem, no rust unit to start with. You should be able to do that for less than $3500 dollars. You would spend much more than that just getting either one of these junkers running.
