They should have both. I like to buy this kind of stuff local also - much easier to return, which seems to be necessary all too often. I believe the only difference between power and manual mc for a given configuration is the depth of the pushrod hole in the piston. If I recall, the power mc has the shallow hole and the manual mc has the deeper one, but it’s been awhile... How did you determine the one you got was a manual rather than power? I’m pretty sure last one i did this I got it at OReilly - for a 71 C20.
