Sorry it took so long to respond but I just got a new laptop and it's been a while since I had the time to get it online.
Unfortunately I do not have any of the cylinders left at this time. I am currently talking with a small fab shop in Columbus to make some more of them. The cost of the material has skyrocketed but I believe when I do have them again they should be less than $20/ea.. The projection is that they could be available as early as July 11 but I would say expect them about August 1.
As soon as I get some I will definitely let you know and will get you as many as you'd like.

Hello read your post regarding the new gas cylinders for the Yugos you made up a long time ago and was wondering if you had anymore available? My email is budspawn@tampabay.rr.com if you do have some I would like to buy one or two of them. My zip code is 33708 if you want to work up a price as well. :-)
