Thanks for the offer A10 JWO...I actually checked a couple of Ebay sites last night, bonnie 140v has a lots of SS spacers, will also make to your own specs. I'll also check out your suggestions.
I also checked out PN 42-6900, according to the parts book, it's the smaller of 2 cotton reel spacers, the longer ones are for a 2 piece rear stay, and the short ones are 3/4x3/8x1/2 long, which would be short for the dimensions I have.
Building a RGS replica from parts sourced from all corners is a great way to spend the winter in Canada (todays high, -25C...-40C if you live in Winnipeg) I've come to the conclusion all you need is a credit card with no limit lol, which I don't have, but so far so good, things are moving along.
The frame is a modified A10, modified swing arm and forks to take the correct wheels (well not exactly, the rear is an 18" not RGS but available on GS) sourced and modified here in southern Ontario, the motor and gearbox is a fully overhauled, Super Rocket, 1959 also purchased here in Ontario, including overhauled mag/dynamo..clocks, tank, seat, UK, pipes UK, paint for the tank US, and paint job here in Ontario...clocks, I think I gave my first born. But I'm lovin the build. Most of the fit up is done(other than spacers etc) I'll be stripping it down this week and taking it to the guy that did the tank for me, cleaning, pressure test etc, for him to do a bit more work on the side and center stand, and also fit a couple of rear set stub pieces. Whether I use them or not is still undecided, but I'd rather have them there.
Thanks again.
