Thank you all so much. I now have the answer in your replies and will now take a look, working my way through them. having the drums skimmed hasn't helped the situation, with new old stock Lockheed brake shoes fitted, and fully adjusted, so will def need oversized shoes or shim the snails. Will measure the drums as stated first.
One question to be clear. Should the brake shoes at rest measure just shy of the 7" brake drums, thus minimal clearance with adjustment for ware, if so I can measure the difference and have oversized shoes made up for starters then move on.
Regards Rob.
ps I will report back when I've sorted this problem for future ref.
