So Ebay asked for my tax ID before I could put anything else on their site . BS , I've gone over to FB Marketplace with great luck .people need to stop putting stuff on FB Marketplace........
It is a rabbit hole.....
I have a 780 holley on my pickup. I use it ONLY for towing my big trailer and haven't moved it since june fo 2018. When I'm towing it I use all the 454 can give me. Had a older 650 on it before and it took a dump and threw the 780 off my old chevelle drag car and what a difference,One of the "junkers" I drove in the '70s was a Pontaic station wagon. It had a 455 engine and a two barrel carb. Thirsty around town, but on the road (at ~80 MPH) it got exceptionally good mileage. I think a '72 model, just before EPA grew teeth.

If that steady is 5" across the base it looks like it is for a Hardinge HLV, and they sell for pretty good moneyOne of those deals where waiting and watching pays off. $30 bux, plus some shipping. It doesnt rate a "You Suck", I have some work still to do to make it fit. But for under $50 bux total, I got plenty of patience. Good heavy iron, not some import flimsey toy. I suspect a little old fashioned, it doesn't open up, and the screws need to be refitted for length. But to fit the Atlas, all it needs is a flat bottom plate. I have a steady for the small machine that has been refitted with small roller bearings. Now I got one for the big machine. It is 5 inches from the top of the clearance, 6 inches to the bottom ov the "V" ways. A perfect fit for a Craftsman/Atlas 12 inch machine.
