Window Regulator Pivot: which one?
 

Well dang! I disassembled the door to replace the window felt guides and there, in the bottom of the door, was the now-detached window regulator pin.

So, I look at the ones for sale by our host and it seems there are two choices: 23mm long and 26mm long.

As you can see from the attached photo, mine is approximately 16mm long.

Where can I buy a correct one for my car (1987 911/M491)?

I really just want to buy the thing and not fiddle with fabricating my own, if possible.

Before someone scolds me for disassembling the door and puling the door frame to replace the felt, I'll just say that there was [factory] adhesive on a small section of the original felt tracks... too much old adhesive to allow the "easier" method of replacement.

It's always something...

common problem
There is no replacement sold - the part that fell out is not a pivot (the parts that are sold that no one needs).

I had these machined. These are 23mm long.
Most probably the ones that Pelican sells have this shape.
Your piece is different and shorter.
If you buy any of the two from Pelican you can modify it with a saw and a file to make it similar to yours.
Or if you have access to a lathe you can machine one.

It looks like your pin sheared off under the head and that is why it’s measuring short. Not sure what size you need, but I just replaced mine and it’s a pretty easy job. My car is a ‘69 and I needed the 26 mm pin.

Your part goes where the black arrow is pointing, my parts go where the red oval is placed.
Different parts that is why your's is shorter.

Yes, thank you. I figured this out yesterday with the help of photos here on the forum (probably your photos, thank you!). Since my window goes up and down just fine, smoothly and even faster than many I've seen (especially with the new felt tracks), I just buttoned the door back up.

This item has to be one of the best examples of a poor design.
It is soft white metal that has been swaged/press fit into the hole with no fastener.
It is also sees a good amount of force in shear, and is too short allowing the spring to ride up which compounds the force on it.

If you buy and then machine the part suggested - take it a step further and figure out how you plan to fasten this new machined part. Tap and thread?

Dan, I agree. Whomever designed that, wasn't paying attention. Anyway, as much as I appreciate, your help on this, I'm not about to open up the door again just to get a slightly faster window raise. Have a great weekend!

Fixed mine with a bolt and a short threaded coupler. Ground the head of the bolt head down once installed to provide clearance. Getting the end of the wound spring on to the coupler was the hardest part. Don’t spend a lot of time/$ on this fix!

My sentiments exactly.
Hopefully the designer didn't work on the brake system.
