Hello e-buddies.....looking for some help identifying some last bits of hard ware from my 73 challenger engine bay restore .....
Notes.....

#1- has littleteeth as if for grounding?

#3-i believe these are for battery hold down....although I am almost sure before I started they were being used to secure the radiator with 1/4" threaded studs but I haven't seen this method referred to anywhere.

#5- wiper motor to linkage nut?


Thanks in advance

#1- has little teeth as if for grounding? I would say for fire wall blower motor ground.
#3-i believe these are for battery hold down.(I would say if they are 5/16"). .although I am almost sure before I started they were being used to secure the radiator with 1/4" threaded studs but I haven't seen this method referred to any where.I would say you are kind of correct. 71 uses bolts. Depending on year. # 5 below picture is easier to explane. Other may know better.

Hello and thanks for the reply. I found an old picture that confirmed the odd looking nut was on my wiper motor. My blower motor ground wire is landed under the bolt for my ignition module. Not sure which is correct but I do agree those nuts appear to be for grounding.
