Gee, thanks Raiyn. We're friends again, huh?
A couple of other pieces of unsolicited advice:
Don't do up the allen bolts too tightly. Otherwise the little ridges on the cleats will dig right into the plastic sole. The result will be less space between the sole and the cleat. You *will* be able to clip in, but there will be no float... your foot will be locked in a position which, unless you are very lucky, will be uncomfortable and likely to cause ankle or knee problems. You also will have trouble clipping out irrespective of the L/R configuration.
A little story. I lost a bolt out of the right cleat somewhere on flights between Hobart and Perth in October (my bike shoes are my all-day shoes). I clipped in outside Perth Airport, then promptly fell over because I could not clip out. I fell on to an already broken shoulder. Ouch!
My paranoia overcame me and I reefed down on the bolt too tightly, resulting in the problems outlined above. I rode for 1200+km before doing something about it, and suffered ITB problems along the way.
The best thing to do is get some Loctite 242/243 and put a few drops on the threads of each bolt before screwing on the cleats. This will serve two functions -- stop the bolts coming out, and stop rust from seizing the bolts into the inner plate they screw into. The cleats are brass and will eventually wear down if you walk a lot in the shoes they are fitted to. At the same time, the heads of the bolts will wear, too. Trying to get the allen key in then becomes a bear, and if the bolts are seized in by rust, you'll likely have to get the old electric drill out and get to work on the heads. It's messy.
I noticed in my hunt for cheap Loctite in Perth that the company now offers small plastic sachets of 242/243 for about a third of the price of a full bottle. I still carry the remaining drops in the sachet in my on-bike tool kit when doing extended tours or randonnees. It's available from car accessory joints.
By the way, welcome to BF and because you are from Melbourne, drop over at the 24/7 party on The Aussie Thread in Road Cycling sometime and introduce yourself to the boys.
