Hi,

I am wondering if V0-435 cylinders can be used as replacements for the
original 0-290 jugs.
This is for non-certified use. I have also heard of an O-320 cylinder
modification. If anyone could give me some advice, I would greatly
appreciate it.

Thanks!

Gene

Go O-320 cylinders. There are shops who will modify your case for you.
