[oletrucks] Hydraulic Lifters or mechanical?

[Dana Muise <danam@spazzco.com>]

Howdy, I have a '59 235 stovebolt, can anyone tell me an easy way I can 
determine If I have hydraulic lifters or mechanical?

Also, I heard a special  tappet wrench was recommended to adjust hydraulic 
lifters, instead of a screw driver and box end since the motor needs to be 
running. Does any one know where to get one of these wrenches?

Thanks! Dana
