WIPER MOTOR #
I need some help from Bill I think. I have a 66 F100, last 6 of VIN are 746604.
I have 2 speed wipers and need a motor. The number I am finding for a 2 speed from Cardone is 40-258. It is listed as a 2 speed motor but for VINs after 78xxxx.
Anybody know what 2 speed motor will fit my VIN?
Thanks in advance
Mark

Despite the 1970 part number prefix (D0TZ), the only applications this 'service part replacement' 2 speed motor has are:
1964/65 F100/350 & 1966 F100/350 before serial number 788,001 / 1964/65 F500/950 & 1966 F500/950 before serial number 802,001.
D0TZ-17508-A = 4 available NOS / C4TZ-17508-H = 6 available NOS
---------------------------------------------------------------------------------
C7TZ-17508-D .. Two Speed Wiper Motor (Motorcraft WM-225) / Obsolete
Applications: 1966 F100/350 from serial number 788,001 & 1966 F500/950 from serial number 802,001 / 1967/79 F100/350 / 1978/79 Bronco.
Post #2: This is the same motor Mr. Wilker used by changing the arm.

Probably the differences will be the electrical connector end. I've done about a half-dozen intermittent wiper conversions and use the later, very abundant, mid-to-late 70's F-series wiper motors (my Falcons and both my 66 and past 67 F100 have this motor now). As long as you get the switch to go with the motor the wiper motor can be just about any from any year as long as you use the correct arms, transmission and mount bracket.
When you mount everything pull the wiper arms and blades off and run the motor without them to check it all - then park the motor. Only then install the arms and wiper blades. Don't expect a new wiper motor will park at the same spot as another one. You can also risk powering up the motor and plowing your wiper arms into the cowl.

Without swapping what, exactly? I'm not clear what you need to know.
Generally the motors all have a bolt pattern that is the same - if they mount up inside the dash anyway. The brackets may all differ, as well as transmission and arms. Those that hover outside under the cowl, I've no idea. Have never swapped one of those out. But I've used 3 F-series motors on my Falcon projects and added the same later motors and wiring to both of my pickups and a couple friends cars.
I'm not sure the exact year they swapped the wiper switch connector but they did at some point so I use the later switch so I'm not splicing and swapping connectors. Plus, even if I don't have the intermittent module, its a simple unplug connector and insert module to add it later. Always on the lookout for those when I bone-yard pick.
In theory when you mount a motor with your original arms and transmission it should park close, but I have only once left the wiper arms and blades on and for whatever reason when I turned it on the motor wasn't (perhaps) parked when I put the wiper arms and blades on. Learned quickly to never assume. Plus its better to test a new install without dragging dry blades across the windshield.
I did a pretty detailed outline on adding the later wiper setup in my 66 truck build... linked below.

OK, I am working with a dozen plus years back since I did mine. I disconnected & removed the motor in my 66. I installed the 76 motor and found that it parked the blades in a different place, that was not correct. My recall sez there is a flat spot or something unique that holds the aprox 3" arm on the end of the motor shaft. That flat place holds the arm stationary, gives it the grip to move the blades. I noticed when I did mine that my 76 motor arm was different than my 66. So I mounted the 66 arm on the 76 motor and the wipers parked correctly when tested. Not sure where my delay switch came from. I did find that there are two kinds, ones that rotate and ones that slide. As long as you use the one that your switch space needs I don't think it matters much. Our trucks do require the rotating switch.
I think we may have done this differently if I read correctly. I disconnected the system at the motor arm, swapped motors and switches but retained the original motor arm.
Hope this makes sense.
