This post covers the early type Tiger 1 Rear Mudguards, I have also covered the very first type mudguards as these are what the mounting plates for the mudguards were originally designed for and why they appear to be over size. This post should help you figure out which rear mudguards you need for the period Tiger 1 you are building. If you still need help deciding contact me.
