Using a friends 1984 BB512i, SN 52935, the last one built, and which is a time capsule, I had "correct" Spal radiator fan motor stickers made. This took almost one year to accomplish because getting the right satin aluminum material for the stickers was a real chore. Also, insuring the correct lettering, spacing, etc. was difficult working from a non scale photographs. In addition finding a base material that would withstand the heat in the area in which these are located was a factor too. Mine have withstood a couple of Rally's and driving in Florida heat so I guess they work!
I realize that different year Boxers perhaps had different design stickers, but mine is an '84 so that's what I went for. I think, but could be wrong, the black labels with white lettering are incorrect and were used on later model 3 Series cars or the heater fan motors. Please, correct me if I am wrong. The center Air conditioning fan motor did not have any labels or stickers.
I don't believe for judging purposes, that points are deducted for the missing stickers which seems to be the norm. However, it's just a nice touch to have these on the motors which adds to the overall appearance of the front bonnet area.
Attached are pictures of the main label, the quality control sticker, and the "+" sticker that goes in the vicinity of the positive lead going into the motor. If interested, please PM me at [email protected]
