When I replaced my heater core I forgot to take a few measurements - and obviously I also didn't fasten the ground of my blower motor as good as I should have



I'd need a few measurements from somebody with a removed passenger side fender liner of a '70 Cutlass:



As you can see a corner of the duct slightly rubbed on the liner at my car, don't know if this is common. The size of this rubbing location is about 1" in diameter.

Starting from the bottom:

* Center of the rubbing spot to lower screw hole (fender liner mounted to frame)

* Center of the rubbing spot to edge of fender, straight to the right, straight angle on fender edge

* Center of the rubbing spot to the edge of the blower motor.

You may have guessed it, I'm considering cutting a service door into my fender liner...

Thanks!

 

Done. Removed fender liner once again, ground was loose. Thanks
