ISO 2 sets of these. Please PM if you have some extras to sell.
Thanks
Google shows at least a small number of shops with the parts available. And they are also listed as in stock on the Walthers website, which means if you happen to have a hobby shop somewhere close (I know that's not as likely these days) they can almost certainly order the parts in. Or you can order directly from Walthers. And in the worst case, you can get them direct from San Juan Model Company.
Good luck!
