My truck is a 1991 ranger super cab with 4x4, auto trans, and the tick tick ticking 4.0
And idk if its relevant but it has a lift that I've been told is 4 inches

Now that we got that out of the way,
My front brakes have an issue that from my research is very common. The knuckles have warn and chipped off a bit at the end of the brake pad slide. So when my brake pads wear down enough the brake pads decide they want to fall out. from what I've read about in this website and explorer websites my options are to 1: pull knuckles from an explorer or ranger like mine or 2: pull knuckles from an explorer/ranger from 95+ that doesn't have knuckles that wear.
I don't like having knuckles as a regular replaceable item so I've decided to go with the second option and I'd just like to confirm before I take apart my truck and realize I've done something wrong.
To do this swap I'm going to need:
95+ knuckles, calipers, caliper brackets, discs, and pads.
The questions I then have are: do I need new lines or are my current lines going to bolt right to the 95+ calipers. And the other question is do I need different ball joints. The reason I ask this is because I just did my new ball joints at the end of this last year. I'm okay to buy new ones I'd just like to save money if I can reuse them.

Sorry for the huge paragraphs, I didn't want to leave out any info that you wise guys might need. Thanks in advance
