? Front and Back bolt sizes for leaf springs

1999 xj, 4.0

I am planning to change out my sagging leaf springs, I have been doing my research, but I have not been able to find a thread with the exact size bolts that go through the bushing into the frame, front and back? I like to have them in advance before starting the job.

Does anyone know the sizes or where to buy them?

Also I been spraying them with PB blaster and plan on heating them with a torch to get them out.

Where do I heat when I can only see the head of the bolt, and the rest is hidden in the frame, it also hard to get pb blaster on the ends of the bolts because in some spots there is no access like in the back by the shackle.

There is a small shoulder on the bolt too. Dealer here sells new bolts for approx $15 each, I use the LCA bolts from the junkyard

LCA bolts ftw. Easy to pull, almost never rusted in, and cheap to free at the yard...

I just double checked my catalog (94-96, not checking the other years) and the XJ LCA and leaf eye + shackle bolts are all exactly the same part number. As has already been mentioned the WJ LCA bolts also work (and are usually in great shape) and ZJ/TJ bolts may or may not work since they use a cam bolt adjuster on the front LCAs. The ZJ I put new rear LCAs in had some very familiar looking bolts but I'm not sure if they are the same length.

Got it - thanks all for the help..

x3 for the LCA bolts. I ordered mine through TeamCherokee because my local dealers wanted some absurd price
