LCA Eccentric Bolts

While removing my D30one of these bolts sheared. I searched and found that these type bolts are exclusive to 97. True? I am adding RE LCA's and swapping in a Rubi D44. The mounts on the D44 look identical to those on the D30. Do I need to replace those bolts with new eccentric bolts? Or are some new grade 8's okay to use?

Those eccentric bolts adjust your Caster angle. Many people (inlcuding myself) buy those to adjust our angles instead of buying aftermarket control arms. You can get away with grade 8's, but i'm not sure if it'll set your caster angle at the correct specs. As for getting those bolts, the only place I know of that sells them is the stealership for about 24 bucks....for a stupid bolt.

So is it true that 97 was the only year those were standard?

Yep. They are a cheap and slightly effective way to adjust your caster, but at the expense of damaging the control arm mounts.

There's really not enough clamping surface at the bolt sleeve to keep the mounts in place if you stress them.

The non eccentrics use the big round washer locked into the horseshoes to help somewhat. Slotted holes are a fairly poor system overall given how much stress the axle can see when you put on larger tires.
