I assume 40 / 50 mm is width so don't have to worry about 203 or 200 as only see 203/40 or 200/50 on ebay...
Thanks in advance
Yup, the easiest way is to measure the width of the shoes you have, or the depth of the drum face, that the shoes push against.
3mm is quite easy to lose on a drum - especially a boat trailer one that's been dunked a bit!
Should be plenty of places on line, if not give me a shout, they're always in stock. Don't pay more than £50 for an axle set (i.e. two pairs of shoes and two sets of springs: enough to do a complete single axle).
Have a look in the trailer stickies thread - I put a couple of vids up in there (via YouTube) on how to strip and re-fit Knott shoes.
All the best, Ben
