My truck is a C10, 1968 and has the narrower top part of the frame.

I have the BHS511

I think you are going to be ok ordering the 63-67 Holley part number you reference. If you go look at the pictures of the BHS511 and BHS538, you can clearly see that part the rests on top of the frame is longer(on BHS538) for the earlier trucks.

For the factory engine stands I have never seen any being sold as specific to C20 trucks, so my assumption is that factory C10 and C20 engine stands are interchangeable.
