Manual valve question

[**grumpy**]

A few years ago I had a 59 Chevy wagon that was bagged.

It was only 2 switch, 1 front 1 back.

It used some kind of manual paddle valves. The valves were on each side of the center console and the air escaped into the console when airing it out.

Any idea if theres something like that available thats not expensive?

I see some on ebay for 20 bucks each, but not sure how they work.

I just want to bag the front of my torsion bar equipped 60 shortbed, to do away with the torsion setup.

Money is a real issue right now. Cheap cheap cheap is what Im after to get me by for awhile.

Thanks
