Installed the Altman latches on my 51, 3100 and love them.
I made a template of the passenger side lock assembly hole and took measurements of its location. Transferred that to the drivers door and duplicated the hole. Take your time, it’s not that hard. I test fit a new lock assembly and it worked great.
Yes, you do have to cut a slot in the door for the retainer. I used a die grinder with a cutoff wheel.
I thought about electric locks but couldn’t figure out a manual unlock function in case of power loss, as might occur in accident.
