Hi Tomcat,
I've taken a deposit now - so it's all sold pending payment but... on Facebook (British motorcycles and parts for sale) someone (a Samantha Hague) is selling - "For sale. BSA A7 rigid frame cam followers, (4). £60 plus postage". Don't if that helps?
But, the guy who has agreed to purchase my spares is a well known member of the A10 Forum - and I'll happily mention you'd be interested in the cam followers and see he's ok with me forwarding his details? You still may be able to buy from him?
Hopefully you get the parts you need?
Regards,
RoadRunner
