YJ Torque Specifications

I'm bored, VERY bored. So I thought I'd crack open a repair manual and list all the torque specs in a thread so that they will be searchable for future use.
Not sure if this has been done before, if so - then I guess we have some redundancy.

So here we go. Below are all of the torque specs of all the bolts listed in my Haynes Manual for the 1987 - 2003 Jeep Wrangler.
Or course I'll leave out all the non-YJ specific ones.
I'll get what I can tonight, and then work on it more tomorrow night. And then I'll clean it up and catagorize it better after that. Right now I'm just wanting to get the information typed while I'm running a very long and boring job here tonight and have free time.

Tune-up Specific Items

Filter Screws 30RH and 32RH - 35 in-lbs
Filter Screws 42RLE - 45 in-lbs

Well folks, that looks to be it!
I'm going to go through the book and see if there is something I missed. If anyone wants to chime in and correct me or input something that I missed please do so.

I was wondering about these values

Oil Pan Mounting Bolts 1/4 x 20 - 84 in-lbs
Oil Pan Mounting Bolts 5/16 x 18 - 132 in-lbs

Anyone has these on ft-lbs? I am not very good with numbers and my torque wrench comes with ft-lb or Nm graduations, not in-lbs

Thanks

...Just like you divide inches by 12 to get feet, e.g. 36 in./12 = 3 feet, take the in-lbs and divide by 12 to get ft-lbs. 84 in-lbs/12 = 7 ft-lbs. 123 in-lbs is 10.25 ft-lbs.

My FSM lists 28 ft-lbs for the bellhousing to engine bolts, and 27 ft-lbs for the bellhousing to transmission bolts.

I've been trying to figure out the torque specs for the body bolts. I just bought a daystar kit, and can;t find anything in the manual on what to torque them to.
