Toyvo - No I've not... but I have been to Kimswick. Nice little day trip get away. Next time there I'll definitely check it out.
Everyone - OK... got to buck up and buy some cylinders. It's nice to know how to handle this if (in some future time) the cylinders are not available. It's always nice to know how to rehab instead of purchase new. Sort of my motto for the work on this truck.
Thanks all!
