19 mm adjustable from sway bar. I believe this is an aftermarket swaybar manufactured in the 60's.

SOLD!

Thanks for looking!

hopefully more like the 70's

drop links are long, could be 60s

Looks to be an H&H bar. Have the same one on the project car.

i like the way it clamps to the spring bar

That is an H&H Swaybar. I have the same one on my car. They are really nice period correct swaybars. At least more period correct. I'm not sure when these were actually sold but it was at leaset in the 80's if not mistaken. I'm sure there are so old timers on here that will know for sure. It's adjustable!
