vapour blasting is probably too harschthis was what I was thinking, there likely a way to remove the anodising or see if it can be vapour blasted?!
Hi Croupion - can you do a pic of the backside of your spider and one from a lateral point of view. That will confirm if your spider has an offset or not ;-)Well it seems you, Bduc61 and I can swap :
110 Silver VWP -> Croupion
110 Purple Croupion -> Bduc61
94 Purple Bduc61 -> VWP
