http://bikesmithdesign.com/temp/campi-stronglight-3pin.jpg shows 36-46 Stronglight rings on steel Campi 3 pin arms. I don't remember what bolts I used, but the are longer than Campi. I also have a set of alloy 3 pin Campi arms. and the original chainrings from both sets. The crankarm/chainring interface is the same 9mm hole.

If I didn't have the bolts, and was mixing brands, (so originality wasn't an issue) I'd get out my trusty 10mm drill bit and make the rings and arms compatible with modern 10mm bolts.
