I found a few brand new spreaders with the old ummm 'buckle' system if that is the word, at the local tip shop. They look easy enough to convert to a slider system so I am happy and will use them (especially as I seem to break spreaders pretty often.......but then I thought that if you needed one like this for an old harness, you'd never find it......
So before I modify them all, does anyone have a burning need for one of these...?
