Thanks, @rccardr for noting yours has spacers. I'm an old hand at triples, got everything oriented correctly as far as recesses go. I may scavenge the spacers from the biopace I'm not using right now. @Slash5 - yup, it came to me with all Sugino rings on it, though the large ring looks of a newer vintage than the other two. The middle and small look like the old rings I'm used to from the AT cranks I have. You can sorta see in the first photo above. First 'modern' XD crank I've ever had. Thanks to the two of you for the replies. Much appreciated.
