FYI ... I checked the size of the needle bearings from 1 of my OPS .90's ... well low and behold they are the same diameter ... the OPS needles are a bit shorter ... but I don't think it will hurt ... so I had put a bunch of OPS needles into my Picco .90 ... and will be flashing it up soon as the weather permits ... I will let you's know how well this repair worked out ... thanks again Chris
