G28 - Simple Mans, Simple REDO of an G28 LP640

[Simple Man]

I feel your pain, I'm currently working on my inner door as well. I have countless hours into one door and. Not sure when it will end. Keep up the good work!

Thanks!  I was hoping to start on the window install but we had a power outage early Sunday morning that lasted for 30 hours... So zero progress on the REDO!

Dear God! I spent a ton of time getting the twisted inner door to lie flush against the door seal      It was like reconstructive surgery.  Pretty happy how it came out.

Compared the curve of the OEM glass to the opening and the old door that I took of the car. I can already see that I will be spending a ton of time getting the opening correct for the glass.

That's a winner.  Being that we are mounting the latch 90 degrees from the oem Mercedes location, I don't know if the weight on the latch is really necessary and could be cut off.  Maybe someone on here could chime in and correct me on that.  Also the amount of pull to unlock the latch leads me to think that as there are 2 springs on that lever, the stiff spring could be removed.  (I have done this but as yet I haven't finished my doors)  I don't know how this would affect the latching mechanism when closing the door but it would certainly require less pull on the interior release handle.  The OEM release lever is make out of plastic and breakage results are common.  Some of the guys have made handles made out of aluminum.  These are a great advantage.

Boy, you're really stretching my grey matter.  I know that there are a few that look similar but the strikers are different.  My advice is to go with the W115 but make sure that you get the strikers that are the same year as the latches.  Make sure that they are the stamped steel and not the cast ones.  Note that the 3rd picture has the child safety button it (I think that this button keeps the door from opening from the inside).  This latch is from a rear door.
5th picture shows reinforcement placed behind the latch.  It can be welded to the door inner framework for strength.

Thanks 01!

I was able to locate my W115 that I bought in 2015.     When compared to the W126 it is a bit narrower which I like.  It also looks like it would work for external mounting where the W126 doesn't look like that would be possible.   Something to mull over as I work on getting the upper door to seal.

The reason for using the exterior latch is that it is mounted rearward towards the striker.  With an interior latch, the door needs to be moved to the rear and close to the striker.  Look at all 3 of your pictures and you can see where the door is rubbing on the striker.  Hope yours come out OK.

O1 so what latch is it that mounts externally?

Why have you chosen to install the interior door latches rather than the oem exterior latches?

Happy New Year 01! 
I'm not really sure why I am mounting the latch on the interior. Or if I should even use the W126 or the W115.

 I've only seen 3 G28s latch installs and they were both installed on the interior, Murci-Me, MDMurcy and the orange car on you tube.  Looking at the W126 latch I'm not sure if it is conducive to and OEM type install on a G28.

The W115 latch might be better for exterior install?  But will it work on a G28?

If any one has any helpful info, feel free to contribute your $.02, I'm still trying to get the inner door to seal against the weather strip

Bugger...

These inner doors are a really just POS

It great to have nice straight door flanges for the weatherstrip   To bad the inner doors are just so warped. Spent a few hours grinding away.  Will have to add some material on the inside of the doors in a few areas.  Material will have to be added in on the door seal side too.

The upper inner door skin....

Hopefully my part for my door shock will be in a few days

Couldn't find any pictures of G28 latch mounting except this screen shot form a video on you tube.

Here is the REDOs,  have a little clean up to do but getting there.

[Simple Man]

Added multiple layers of CSM to the outside of the door skin. Once close enough to door jam; ground inside down to correct thickness.

Made a one piece plate to mount the Latch to using my plasma cutter, getting better at using this tool 

Good times lining up the latch to the striker plate     

Got a start adding support for the latch.
