I got a set of the non-right angle version of these switches from The Miniking a few years back. I believe he said they were from P76's(Maybe for a glovebox light??). I was told they might be problems with clearance but didn't have any dramas. I tried on another one to make the right angle (its the only difference between the two, one is bent and one is not) but the material is simply too brittle.

All the same, for a 69 car at least, there is no clearance issues with the P76 version of the switches.

Yeap there the ones i bought when i went there during the "weeklong mini celebrations" Real good price i reckon
