Lucas DR3 two speed wiper motors:
I recently bought on e-bay a Lucas DR3 two speed (six wire) wiper motor. The wiper motor was a "new old stock" complete with original box (in good condition) and the original instructions in the box. Luckily there was no requirement for a core.

Now here is the interesting news.
The instructions indicate the following part numbers to be all in the same DR3 two speed "family":

75305
75308
75309 (the one I bought, DR3 , dated 10/58, P/N 75309B)
75310
75311 (the one used on 427 Cobras per the Lucas parts list for Cobras)
75313
75319
75325

Now, the Cobra "factory handbook", the little beige colored cover driver's manual, calls the wiper motor out as a DR3 Model 073152.

Both use the PRS5 or PRS7 rotary switch on the dash (PRS7 is Lucas P/N 34374B or the updated P/N 31957).

I have another Lucas Spare Parts catalogue at home and will check the P/N sequences there later.

The six wire colors are orange, brown, red, white, green and blue. I'm going to wire it up to my PRS7 switch as the Cobra factory handbook indicates.

Hope this helps a little.
