A tenner sounds perfect.
I just bought the guts rather than the turn switch & housing. Bought a few other bits to help soften the blow of the postage which was $30
I actually bought a pair of deluxe chrome door inserts a little while ago, but they must be from a different model as they don't fit my '71.
How much do you want for your's including the back plates? I presume they are 68-71 parts?
