Windshield wiper bolts

87 Firebird

What size of bolts are used to mount the windshield wiper motor to the firewall?

Also what size of nut is used to connect the wiper arm to the wiper motor?




Thanks.

Cool thanks.

I bought this firebird and some previous owner took the wiper motor out.
I found it sitting in the engine bay but no bolts or nut.

Wow, a very special bolt. Look at the taper under the head of that thing. I would never have guessed. Great photo and reply jex3941!
