						Well done!
I'd be VERY surprised if they did ever move, last time I had to undo those bolts on my car, I had to use a 3ft bar on a sidchrome ring spanner, the friction between those surfaces, with the bolst so tight, you'd probably be able to tear the tread of a tyre, or slip a bead before they would move!
Just my 2c but!

						They won't move until something happens to several of the bolts.
That's why Bush65 earlier in this thread was talking about the fatigue strength of the bolts.
If a couple of the bolts get cracks growing through them, the clamp load will drop.
You'll probably notice them leaking before they shift if this happens, but the steps he mentioned earlier to help bolt life (i.e. thick supporting washers) are a very good idea.

						have done the same on our D1 and they have NEVER moved, even with upgraded brakes and 35's and teenage rampage....except, the slots were not as profound as these - and I wonder why they need to be so pronounced for the adjustment needed...but as said these should not be an issue provided the mating parts are sufficiently torqued together (but maybe lose the gasket in favour of a liquid one?).
We did contemplate putting a small weld across the flanges to prevent slippage, but having observed no movement from a couple of reference marks placed across the flanges, this was not necessary.
Hi,
I did mine on a 74 RRC some time ago. Worked out how much extra caster I needed from the OL sticky (thanks HSV) and went from there with a slotting bit ($27 odd non trade) a jig, and a drill press.
Bolted the 'slotted' balls up to a spare housing using rusty oily bolts, checked the angles and filled the voids around the bolts with weld.
I am not a good welder, but all I had to do was clean up one surface a touch with a little grinder and they just looked like OEM. Did use thick washers under the bolt heads on reassembly.
Drives the way intended. Great return ( in driving pleasure) for time invested.
cheers, DL
