This is a good suggestion.
I love these plastic pop bases. I add molex connectors and remove the complete pop assembly when I need to adjust the pop spoon and switch.
The only problem with ordering just the bare housing from Pinball Life is that 3 parts are not included that you will need. You need part #9 and #12. The drawing calls these two parts tension plates. You also need item #24 which is called a coil mounting plate. If you have the right tools you can make your own plates but if you don't have the right tools it can be a PIA. You will also need the screws and related hardware.
Pinball Life sells the complete pop bumper assembly and those 3 needed plates are part of the package, but PL does not sell just the plates. If you order the complete assembly, for the Sterns you need to you need to order the AE-26-1200 coil. The coil is not equipped with a diode so you have to add a diode.
