Anyone know the front eye bolt dimensions on the rear springs? I'd like to replace my rear springs and am anticipating having to cut them. I searched to no avail.

Google is yr friend bro

this is the 1st thing I came up with

factory leaf bolts are M14 x 2.0 pitch x 120mm long, class 10.9, flange head, nipple tip

done a few...saturate with penetrant via holes in the frame rail for 2 weeks before, use 3/4" drive gear

Dont cut the bolts unless you have no other choice. Since you are replacing the leaves, cut them off at the eye. Then cut some grooves into the eye so you can pry it off the bushing shell. Do the same for the shell and pry it off the sleeve. Cut the rubber with a knife. Find the groove in the sleeve and cut it there. Pry it off. This will leave the bolt exposed. Grab the torch and heat the bolt up to loosen the loctite. The trick is to NOT break the captured nut off inside the frame. It does happen. BTW, the bolts like to rust to the sleeve. Theres a thread floating around here somewhere on cutting the leaves, etc.. I can never seem to find it, but i know it exists. Ive seen it.

Use PB Blaster, not WD40. WD40 is a lubricant, not a penetrant. Regardless, you will more than likely need the torch doing leaf springs.

x10. Somewhere there is probably a picture of an old can of WD-40, which does NOT claim to be a penetrating oil. I don't know when they started making that claim, but it's bogus. A number of controlled tests have put it dead last in penetrating oils. Just barely better than nothing!

There! Ah fixed it fer ya!

I was able to get leaf spring bolts from the dealership when I did this job, but there are probably cheaper ways to get them. This job was a major PITA, but ultimately worth doing. The previous advice is right on.
