Bolt on Rear Sway Bar ID Help

[SS69chevelle]

Hello all, I wanted to check and see if anyone knows the year and maker of this rear bolt on sway bar. It is 36 inches wide from outside of link mounting holes on bar. Clamps to a rearend housing using four 5/16 bolts to clamp the sway bar and two longer 3/8 bolts to clamp to the housing. Appears there are some small brackets for the body attached parts missing. one of the clamp brackets has red or orange paint that appears to be original, maybe Ansen or other aftermarket vendor? Any help/info would be appreciated, thanks Andy

I decided to clean the bar off and found some letters cast into it by the link bolt hole. they look like they are inverted from casting, does anyone recognize the letters and or know the company they belong to? The first pic is the way it is on the bar, the second pic is reversed. Thanks for any insight or help, take care, andy

I reached out to ADDCO and they reviewed the pic and said it was not one of theirs and they dont know who made it. I am still in need of help if anyone recognizes the letters or mounting method and can id the manufacturer and/or year. thanks sYc. Andy

I don’t know why they say it’s not an Addco when their name is on there. It looks similar to one I had in the 70’s.

thats what i thought too. the second letter looks like a P capitalized or another font than the others, guess i will have to keep searching for now. thanks for your input. Andy
