Hi folks, after breaking the front arm on my B44.2 the other week I found the bag of spares I got with the car I purchased for my daughter and in it found what looks like a beefed up B44 front arm but on looking for another I can't find any the same anywhere on the net so I'm a little confused.I even thought it might be from a BJ4 but apparently no, anyone got any ideas?
