Ok, let's talk pop bumper rebuilds. Vid's guide is fantastic but I don't think he talks about Gottlieb pops in particular and so maybe this will be helpful to someone, who knows.
Here' the old pop assembly, ready for rebuild.

Don't lose this little spring!

Now, if you take a few more steps you can make your soldering life easier. I learned this one on this project. Trying to solder around the main pop solenoid mech is a royal pain. So, remove the mounting plate that screws to the playfield and use that to mount your plastic pop body to. Then you can thread your new lamp socket through and solder it with everything out of the way.
Remove these three screws.

Screw down your mounting plate.

Thread your completed pop assembly though and secure to the plate with the two mounting bolts.
A little planning will help at this step. Make sure to mount your socket with the polarity correct. Try to see which side the hot wires come in and which side the ground comes in from the wiring loom. Most of the pops I have seen have the hot wires coming in through one of the openings in the mounting legs for the solenoid mech. Note that the leg on the socket with the bend in it is ground.

Soldered together, I like to replace the plastic solder joint covers. They are often pretty crusty.

While you're in there, take apart and clean the solenoid plunger, spring, etc. Replace the coil sleeve.

Nice and shiny! You can buy new collars and springs but these are ok for now. If I had to do it again I'd probably buy the additional new parts but oh well.

The wrapper on this pop disintegrated in my hands so I printed a new one. Yes, I know it's supposed to be off white. 5 demerits.

Make sure your lighting wires are running as freely as possible and away from the main mech to avoid vibration as much as you can. Then mount your spoon switches and make sure they work correctly. I also take the time to clean the contacts and gap all the contacts while I have the playfield on the rotisserie. Hopefully that will make my life easier later.
Got two of the four pops rebuilt tonight and completed the rebuild on the 5 target drop bank. Tomorrow the plan is to tackle the third upper pop and get the upper area of the main playfield completed.
Not looking forward to rebuilding 4 flippers!!!
