Vari shock o-rings

[1911Colt]

I need to rebuild 4 Vari-shocks for my Storm. I could probably skimp on the process as only 1 is leaking, but I would prefer to replace the o-rings as they are the originals. Are the re-re shock o-rings the same as the smaller ones in the Vari-shock? They look the same, but obviously that is not good enough. Worst case, I will scrounge through the leftovers I saved from my Bosscat to find the best ones.

U1818 is always out of stock.
