I am having trouble with getting the correct wiper motor. The car is a 69 SS. When I got the car it had no wiper motor so I can't use that for reference. I don't know if I have hidden wipers or not. Can someone tell me how I can tell? I do have a plate that was with the car that bolts up to the oval hole on the firewall. The plate has a smaller round hole in the center. I am seeing 1st design and 2nd design also. Thanks in advance for your help.
A Malibu with the SS396 option will have concealed wipers. Generally a 300 Deluxe with the SS396 option will not. However, a concealed wiper option was available on the 300 Deluxe Chevelles. Check your VIN: 13637 is a 'Bu.
There were two different concealed wiper motors and either the 1st or 2nd design motor will fit your wiring harness.

I do have 13637 built in July I assume with a 7A on the trim tag? Don't know if that would be 1st or 2nd design. Would it matter which one I get since I am replacing the complete wiring harness?
There's 1 switch for the depressed/concealed wipers (this one fits both the 1st design concealed/depressed wiper AND the 2nd design concealed/depressed wiper) and a 2nd switch for the non-depressed/non-concealed wipers.
I was wondering about that, my Malibu had non concealed and I installed a new concealed motor and it doesn't work (not planning on being out in the rain but Fl you never know) but mounting was the same IIRC, just something for the OP to think about
Thank you all for the great info. So are the electrical connectors themselves different? I don't think they are I just want to make sure. I am not trying to be correct with the proper one so I might just as well run 1st design because I can get the washer pump with it wouldn't you think?
Yes the connectors are the same. The only difference is where they plug into on the assembly. You should be able to get both designs with the pump. If you have a 69 I would go with the second myself. Maybe other 69 owners can confirm that for you.
This is indicating that you have the non concealed wipers. The plate was used to adapt the motor to the firewall. The concealed wiper motor did not use the adapter plate. It also used a specific linkage, motor arm and and lower stainless plate along the bottom of the windshield. The small post that the articulating arm the concealed wipers used will not be present on the drivers side where the arm attaches to the transmission.
Wiper arm and transmission differences
I may still have both set ups from parts cars. PM if interested.
Not meaning to hijack or anything but mine has the NUB but also had the non concealed motor but I don't remember if it was mounted on the car when I got it or was in one of the boxes that came with the car, the new wiper/washer assembly I bought on ebay was a reman Delco motor & new pump and fit the plate that screws to the firewall same as the other motor, I still have the other somewhere if someone needs it but I don't know if it works, free, my wiper trans arm was the wider bolt version also
I do have the wide bolt adjustment on the arm, and the chrome bottom piece. I also have the pin that sticks out for the wiper arm to attach to. Now my problem appears to be that the top of the pin which looks like an e-clip goes on to hold the arm has sheared off on the tip. I see Ground Up sells this pin. Has anyone else run into this and is it easy to replace?
The Ground Strap is a length of copper that you should be able to see on the vendor's photo of the Wiper Motor. It should be included with the Wiper Motor.
I see that The Parts Place carries the 2nd Design Washer Pump.
