Are the measurements the same? Can I just cut off the brackets and weld on new perches?
 
Its a guess. I bet the TJ short side front is a bit more open for all the link and spring mess. Either way your gonna need the perch width and center on what you have.
Are you talking about just measuring back from the knuckle or backing plate to locate the perches?

Went and snapped a pick of a tool I made years ago to help layout axle brackets regardless of width. Helps measure and transfer components without the diff throwing things off.
Your welcome to borrow it. Similar could be built out of most anything.
Set width, center, mark, repeat. I set it in the center pin hole. Center and done.

Rear axle. Should be easy. I like the jig
 
I was spitballin an answer. Your auto corrected title and question has me thrown off.

Are you swaping to the coils and links from a previous leaf spring axle?

If so I like to set the pinion up on the stock to a set degree. Record spring mounts angles and related. Get all the related spacing and then you can accurately duplicate. I've use pointer levels and digital. Digital makes it fool proof.
 
I'm taking a 97 TJ rear axle and putting it into a 95 YJ.

Or you could put the axle under the rig, center. Then locate forward/aft. Tack the brackets on. Test and weld.
 
Should be same width, bolt pattern, pinion centering, etc. But if it's a TJ axle, your options are D35 which sucks, or neutered D44, which also kinda sucks. For leaf springs, just sell the TJ axle for a couple hundred and put in an Explorer 8.8. They were available in 3.73, 4.10, and maybe even 3.55, within 1" of same width, same bolt pattern, close enough pinion location, etc. And leaf spring. I think they are almost a bolt in, other than you need ZJ parking brake cables and maybe a different pinion yoke adapter.
 
I would go 8.8 swap. you get disc brakes, stronger R/P, get rid of the C-clips and you only need to move spring perches. The Driveshaft adapter is about $10 from the Junkyard. Pretty easy, weekend swap as well and you don't have to cut off link brackets, coil buckets etc.

is there a version of the 8.8 that doesn't have c-clips? I thought they all did
 
I seem to remember a c-clip eliminator kit, but I can't remember the manufacture..
 
C-clips are more of an annoyance than the great satan they are made out to be. They are really only an issue if you break shafts or like taking your axles out regularly just for fun.
