Possibly one of the more common but least noticed part of a vehicle are the footman loops, those things to fasten a strap to.
For some reason there are a large range of types and sizes. Obviously for a given strap size, the width needs to suit but there is a large variation even for a given size.
I first found this out when I restored my M5 HST back in the late 90s. It has 18 loops with a 2" screw pitch. All the available loops were different. Everything from 1 7/8" to 2 1/8" and beyond but nothing that would fit. The particular loops were a distinctive design too so I decided to make them.
Having recently been making some hood hoops for a different vehicle, the same loop, an Eberhard EB-6409B was needed again. In this case, as the hoops were new build, any loop could have been fitted but it was decided to get it right and make some more. Here follows a photo essay of the process.
