I fitted it but, unfortunately, due to the mounting lugs being several degrees from vertical, it hasn't made the difference I'd been hoping. I have various theories why the lugs were 'leaning over', but that fact remains they should be vertical. The result of this is the front brake pedal, which also bears against the stop, seems to be rather high and not easy to operate in that position.
This will entail welding a couple of pieces of 4mm mild steel to the front of the stop plate, which will: a) lower the brake pedal slightly, and: b) make the centre a bit more upright, hopefully raising the front wheel off the ground.
I just need to 'persuade' a friend of mine in the garage business to do a 'spot' of welding for me!
