I thought I'd remind everyone that if you split the caliper, you should use the square section o-ring and not a regular round sectioned one. The square section ones are generally available where ever rebuild kits are sold and may be part of the rebuild kit.
Somewhere around, I have the torque figures (there are two different size bolts, and Girling never released the figures. Easiest (closest) way to see what the torque should be is to use a beam torque wrench and note the break-away torque) to use in resetting the two halves together. It's close enough. Proper name for that seal is "Quad Seal" and usually not in the standard rebuild kits (since you're not supposed to split the caliper), but most of the usual suspects have them.
Needless to say, rebuilding calipers is one of the more enjoyable repair jobs on these things. OK, I'm strange.
