Hi Ric,
I've been watching the progress of this, It's a great build, nice work mate.
Just one thing I feel I should mention, don't want to put a downer on this but just keep an eye on the seal retaining clip rings on those calipers. I had an issue with mine.
I did post up a thread with photos but can't seem to locate it.
The ends of the rings curl inwards slightly and cut into the new seals. I returned mine back to Bigg Red for a refund and forked out for Toyota items.
It's just an issue with the band types and not the round wire type clips. If you look at yours, you might notice that the seal will be pinched at the gap between the rings.
It may not be an issue at all but I don't like taking any chances with brakes.
