yep, 7 on both sides. I couldn't find a part number on them anywhere, but i really didn't scrub off any grunge. Anybody know what they are?

Not by sight. But there were not that many 7 leaf a-body applications. It could be a right side SS type spring or some shop's leaf pack. It's odd there are no spring clamps on either side. Leaf packs always come with clamps on both the front and rear segments. Drag racers will sometimes remove some or all of the rear clamps.

Springs today are made by Triangle Manufacturing, Stanley Spring (Harrisburg Pa), Eaton (Detroit) and maybe a couple of others. The first two do not retail direct. Most spring shops will be getting their springs and parts from a manufacturer with a furnaces and heat treating equipment like the three just mentioned. Point is that each manufacturer has their own stamping and number locations or none!
