I have a couple of those that I purchased in error to use on a 69 Camaro. They both look the same. The ones I have are stamped 465 on the back ( last 3 didgits of the pn) and I believe they are for cars with hidden wipers. The 464 looks the same and is for non hidden wipers.
I know when I tried a 465 in the 69 Camaro they worked backwards.
Someone check me on this ? If you need the 465 I will give you one [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]
I think the complete pn is 1993465
