I'm trying to remove my wipper motor on my 71. All 4 mounting bolts are out. But stuck in rubber...and can't see how wipper arm comes off the motor? Any pics will help.Or experience at doing this will help.

 

I believe it's a 12mm nut that is holding the linkage onto the motor spindle, very tight to get your hand under there, it is also possible to remove the motor and linkage as one unit but try your best not to tear the rubber covers and seals, some are still available some are not.

Thanks...bottom rubber mounts were stuck. Was able to move it enough to see 12mm nut.
