Im looking to overhaul the three pop bumpers on my Secret Service which are maybe original from factory and now mushy and cracked. Im thinking of upgrading and colour matching with new parts - and something about the lights is sketchy so hoping to switch to 555 over bayonett.

BUT the original ones in my Secret Service have the older 545-5099-00 bodies which seem to only be available in white: https://www.pinballlife.com/pop-bumper-body-older-style.html

While the newer DE/Stern bodies (545-5197-00) come in lots of great colours:

I think I can just switch to new bodies since the bottoms appear to be the same and so will still fit into the Data East "thumper" or "Jump" bumper mounts under the playfield in Secret Service but I would need to basically replace all the parts above the playfield (ring, cap, etc) to fit the new bodies - is this right? Can the new bodies fit the older DE mount system? Or would I need to redo everything under the playfield too, in which case Ill just stick with white.
