front drums w/o hubs?

I don't know what a shop would charge. The answer to your question may depend on what tools you currently have. I already had a drill press and a hydraulic press, so it was easy to use a hole saw to cut out the drums. Also the lug studs on my hubs were rusty and new ones were cheap, so I wanted to replace them anyway. Now my scamp has new drums, new lug studs and nuts, as well as all new brake parts. If you don't have a drill press you may want to consider using a shop.
