Sorry Kabul Tanker

They are metal walled, They said stock was low, now they don't show any. They didn't cost much so if someone comes up with a better type I may buy them, I'm going to pick up some parts from BYA, they have four things (they have more but not in stock). Metal Barrel 12.50, Drive Shaft Supports 12.50, Metal Sidebar Set 31.00, and metal Reservoir Set 23.00
