Does it look like this?
Fresh air box from '51. The 12v replacement motor did come with motor studs that stuck out 2". I cut them off and rounded the studs to look like the old rivets, and shot black paint to blend. Repainted the housing.
I can't remember where I got the motor. Jim might have been where, but a fresh air 12v replacement is what I looked for.
