upper and lower control arm bolt setup

I decided to upgrade my lower control arms and went with some tubular ones from ebay for 99$. The thing is I noticed my uppers do not look so healthy and want to replace them as well. Now my problem is I do not know what hardware to use to replace these with because the stock hardware almost always breaks on me no matter how hard I try otherwise. Can someone tell me the proper replacement size for all four bolts(uppers and lowers). I noticed cam bolts on the uppers I think, but I keep seeing it is usually the lowers that have them. Can someone help me with this. Cam bolts(yes or no), replacement bolts(exact size <m?>x<?>x<?>).

Search for xj control arm bolts. Plenty of results out there.

Searching is your friend. A quick browse using the keywords "control arm bolt size" yielded this, a link to a thread to a link:

The cam bolts are to adjust caster I believe on the stock upper control arm. If you're going to upgrade the upper control arm, get an adjustable one, then you just use regular bolts - to cinch everything up. I'm not sure what sizes though.

5-90's web page I believe has all this info on it, if you haven't found it already.

Cam bolts do not exist on the XJ. Caster is adjusted by adding shims behind a plate in the lower control arm pocket. Toe is adjusted with the tie rod and drag link. Camber cannot be adjusted, unless you want to mess with offset ball joints.

All control arm bolts are normal bolts.

The uppers are M10x1.5x75mm long IIRC. Might be 1.25 thread pitch but if you get new bolts you'll get new nuts I assume. So long as they match.

I just went through this dilemma with the trackbar bolt. If you want a nice flanged 10.9 m10x1.25x75, Polaris sells them for their suspension components. I couldn't find anywhere else on the web that had a 1.25 pitch in 10.9

Real nice finish, quality OEM bolt. Not cheap though.
