Torque specs on diff cover bolts

I am getting ready to change my differential fluid as well as put a pinion brace, poly IRS bushings, and a differential cover brace on. I just rolled over 106k miles, so I wanted to drain all the fluid out of the diff rather than just suck it out through the filler hole, plus I figured I may as well do it that way since I will have to take out the diff cover bolts to put on the brace anyway. My question is this: what are the diff cover bolts supposed to be torqued at? I have searched and could not find anything to help me. Thanks.

P.S. Also, any tips or tricks that anyone has about getting the diff cover off would be more than welcome. I don't know how stuck it is going to be on there from the old gasket. It also looks really tight up at the top of the pumpkin, so I don't know if it would be best to drop the diff a little bit to get to those top bolts or not.

I don't think following the torque spec is all too important on those cover bolts, but the spec is 20-27 ft. lbs.

Thanks for the reply. Just got done...took me a bit longer than I expected lol. I was bummed out though because I had bought the rear cover brace from MN12 Performance, but I did not realize that it was specifically for an 8.8 rear end...I of course have the 7.5. Oh well, live and learn I guess lol, but expect to see a mint condition rear cover brace appearing in the for sale forums lol. Tomorrow's project: put on the pinion brace and the poly IRS bushings...I know that will fit, as the fit is universal.

New question that just popped into my thoughts: should I apply threadlocker to the bolts on the diff cover? I tested one of them today (a day after I re-siliconed it and filled it up with fresh oil) and it just seemed like it was too easy to loosen it.
