Hi did you get ome from where Glen suggested? if not contact me and I may be able to help as my fastback had one but as Glen said a little shaky so I took it of when I fitted door mirrors. Alternativley you can get the 60s/70/s bullet type mirrors and fit them to the doors as I did.
Hello there, Holden Vintage Classics or a name similar to that (supplies) did one that fitted my fastback OK. Little bit of shake as not top quality, but better than wing mirrors. It was a few years ago, but you might still be lucky? Cheers. G.
When I purchased my series IV, it came with a few years worth of old Cut and Thrusts. Not one car had an overtaking mirror. The fitted wing mirrors are really a waste of time so I am desperate to purchase drivers door clip on or clamp on oblong mirror. Because of the width of the door, the clamp must have a clamp width of 14mm. I have looked everywhere with no success
