Back a few years ago I purchased my new wiper motor from Newport Engineering and it was was jam up. I ordered it for my 52 panel and if My memory is correct I used one that had the right bracket , or something like that, and it did not interfere with the chock cable.......i know you have already purchased one but it may be worth looking at if you need.

....it was made by Newport engineering but in actuality I it came from JimCarter at the time.

Just FYI

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
