My meaning was any information about when these various types were fitted would be anecdotal, not the fact they exist, as the part numbers don't help in identifying the dates of those changes...Ian:relaxed:
Hi Craig
That’s correct
The 2” or do rib allows the rest plate to be mounted on a flat surface
The one here is longer & unless the No plate is pressed to accommodate the mudguard rib - it can’t really be used
