Replacement Guide Pins For Tubes

[braintheory]

Can any of you guys send me a link where I can buy those replacement plastic guide pins (those center pieces) for tubes? I bought some vintage 5U4 rectifier tubes dirt cheap that are functional, but missing those guide pins. Thanks in advance!

I'm sure you will get a better response but can I ask why? Also, how the hell would you even affix it to the base? I've broken those off before and I just marked the tube on the outside in between pins 1 and 8.

What I’ve done is compare the tube to one with a base, and mark exactly where the key would be on the base in white out or if you have light color paint available
