Hi Keith---long time no hear! It IS a bit of a tight squeeze to remove the filter cover with the rear cross-member still in-situ, but better than having to support the engine and remove the rear cross-member. Instead of hex-head bolts I use cap-head (allen key) bolts and a right-angle allen-key with the short end (the part that goes into the bolt) cut down so that the allen-key protrudes out as little as possible. I realise that the oil-filter cover will only alighn in one place, but to prevent you having to fish around trying to find that 'right place', put a dab of 'tip-ex' or marker pen on both the cover and the pulley.
Your description of the American driver really made me chuckle, but on a serious note, your decision to fit "daylight driving lamps" sounds very wise. You sound to be very busy---however, don't forget--"all work and no play will make Keith a very sad boy" Life is NOT a practice---it is the only chance you will get to enjoy yourself. Drop me a line when you have a moment.
