I purchased an NOS 3 speed wiper motor off eBay a while back and afterwards discovered that the numbers on it indicated that it was for a '76 F-body. I was planning to use it in my '73 Road Runner, but thought I read somewhere that there was a difference in the park location? I can't seem to find this information now as I'm preparing to install the new wiper motor and linkage. I do have the original wiper motor from the car, but it looks terrible and I don't want to use it. I did open up both wiper motors the other day to look for any differences, but couldn't tell anything different just by looking at them. Is there a way to modify or convert the F-body wiper motor for my application and if so what parts are needed, or could I swap from my old wiper motor? I have read the section in the 1973 Plymouth factory service manual regarding wiper motors, but still am not sure what to do. Thanks for any suggestions or advice!
