Shunt,

it always depends on how stock you want to go... Perhaps I can help. I was looking for one of these kickdown switches for a long time, too. Finally found a good one. And discovered (and bought) a second one at ebay´s that looks very similar but not correct to the bone: the plug-ins on the rear side are not parallel but diagonal. I think this was the setting for all `65 Lemans with V8 engines & all `65 GTOs.










Apart from this minor difference as far as I can compare them they look identical.
Including s&h to Germany I paid $135 but still haven´t tested it. The mounting bracket that´s included should be correct for all 4 bbl Carter AFB but as far as I remember the correct one´s are still available at Ames or CI (look at the last pics, I documented some of my fresh bought "treasures" a while back...)





If you should be interested I can test the switch this weekend and can check once again where I purchased the brackets. There´s even a new plunger available from Chicago Muscle (not THAT cheap for $35) but I didn´t dare to bend open the diecast mantle...

Cheers
