Again, thanks! | | | | Joined: Aug 2009 Posts: 24 Apprentice | | Apprentice Joined: Aug 2009 Posts: 24 | This may sound silly (or even stupid) but is there any logical reason to have the lock on the passenger side door of my '51 Chevy 3600 truck? I think it defies logic but who knows there may be a good reason that totally escapes me. Could someone fill me in on this so I can look smart when people ask me.

"back in the day" it was a safety issue about getting out on the drivers side into traffic. In todays world just get you another lock and put one on the driver side like I did my 52panel. This goes back a long way. My 37 has a "knob" on the inside of the drivers door that you twisted, then slide out the passenger side and locked it from the street. Back in those days I guess folks were afraid of stepping out in the path of a horse and buggy!! | | | | | Joined: Aug 2009 Posts: 24 Apprentice | | Apprentice Joined: Aug 2009 Posts: 24 | Thanks, that's so cute I can buy it. It sure makes for a good conversation piece. But I was always under the impression that "back in the day" men were so manly that they could step in front of anything. Maybe the car designers were not part of that group! No offense meant.

Getting in from the sidewalk meant you could avoid stepping in the snow/mud/manure on the street. | | | | | Joined: Aug 2009 Posts: 24 Apprentice | | Apprentice Joined: Aug 2009 Posts: 24 | OK, so far it sounds like a lot of urban legends. Nothing concrete as to the real purpose of this door lock situation. I'm still intrigued and I hope I don't sound too anal about this. I will pursue the issue and maybe I can come up with a logical answer. I don't disagree with the answers so far because I think they have some credibility, but no real hard evidence. Let's say we keep trying. Thanks.

lots of odd little quirks about older vehicles, mostly explained by 2 things: inertia, the way it started [mostly arbitrary] was the way it stayed, and also by a critical thing with these cheap consumer goods, the OEM's saving every penny they could - why put 2 locks on when 1 will do?
Bill | | | | | Joined: Mar 2008 Posts: 3,750 'Bolter | | 'Bolter Joined: Mar 2008 Posts: 3,750 | Paul..Here's my theory on this age old quandary.... Back in the day,these trucks were commercial/farm vehicles. How many times in their life would they be securely locked? Not many I bet. It harks back to a time where it was possible to leave your house unlocked,never mind your car/truck etc. The only time these would probably ever be locked is when they were taken to the sprawling Metropolis of the local town!
I agree with Bill(red58) as well. 1 lock over millions of trucks is a lot of $$$$$$$! F*rd did it with a 50c rubber breather tube,the difference being, THAT cost lives!

I can see that some of you have been through this before and most likely through other little puzzling questions similar to this. Didn't mean to take up your time on this issue but you have satisfied my curiosity. At least now I can look halfway smart when asked the same question and respond using those reasons mentioned above. It should leave peole wondering whether I'm joking, making this up or actually being "in the know" about this issue but leaving them with very little room for argument. Again thanks a bunch.

This topic has been covered several times on this forum, and on other truck forums as well. Makes for some interesting reading!! | | |
