hi bill,

i replaced some of mine. the oem price is like over 150 bucks apiece as well as the newell parts price.

here is the identical ones in aftermarket. i paid 36 bucks for 2 of them last year and i see they are up to 47 for 2 of them now.

as for mounting, they are mounted on a small aluminum plate that is mounted to a piece of plastic that is mounted to the door. all is done with double sided trim tape.

i replaced mine and all was well. i replaced the plastic squares that hold the wires. you can buy them at home depot.

there may be cheaper aftermarket places. i would buy the cheapest ones i could find. they are just door lock actuators, nothing special about them. used in a ton of different ford cars over a 10-15 year period
