The Earlier Commando CHROME steel would be best . Later Stainless are the wider ones .
P R & Fastback rear guards differant .
Might ave youres . Fit wotcher got tho , Anyway !
Bit of a minefield / Threw the 70 Front on old 50s roadolders no trouble .
The Disc Brake forks and guard bracket are wider .
mine on SHORT roadholders , the guard ( just ) dinged on the steering damper
lower fitting .Under the lower triple clamp .
Think the later wider guards maybe neccesary for a 4.10 - 19 front tyre though ? .
