Apparently the crank arm that attaches the wiper motor to the wiper linkage is different on an AC car vs a non-AC car. I need the one for an AC car so that the crank clears the top of the heater box.
Call Kim at Passion4Mopars, she'll know.

I'll give her a call, thanks. It looks like the brackets are out of stock though.
There's different crank arms for different applications, but not different for AC vs non AC set ups. A two speed crank arm can't be used with a three speed motor because one is a concentric motor and one is non concentric and that will lead to binding of the linkage because the bends in the crank arm are different because they operate differently. For a mid 68-70 B Body application, the correct crank arm would have PN 2822273. For an A body mid 68-70 the crank arm PN would be 2882272. If you need some assist, feel free to call or email, we'll figure this one out :-)
There is a difference in the output shaft size, large or small cog, but the small cog will fit all crank arm openings where the large cog output/gear latch shaft will only fit up to a 72 crank arm where the opening was smaller and won't fit the large output shaft.
Thanks for the info. I called Thursday and left a message. I haven't heard back from you yet. I'll try again Monday.
I think I have that arm in my parts box got a few need correct part number to verify
