That is why I was interested in what cars had them installed.
Does your '70 have the factory rear anti-sway bar and boxed lower control arms that came with the F41 performance suspension option? While RPO F41 was included in all '70 & '71 SS454s (RPO Z20) and '72 Customs (RPO Z03) it was also an available option on all other models for all years. Do you have a Build Sheet for your '70?
No it does not have the box lower control arms nor does it have the sway bar. And yes I pulled 3 build sheets.. one out of the back seat one under the front seat and what I believe to be the real one on top of the gas tank unfortunately it was not very legible. So I can't really tell if in fact it was the real one. But no big deal I just thought they only came on the SS or a 4-speed.
The existing 12-bolt rear ends coming out anyway for something that can handle a little more horsepower. I don't want to run C clips either.
I believe they all had them. They were installed to stiffen the chassis a bit. Aftermarket suspension companies like Hotchkis, UMI, Global West, Spohn etc. all make sturdier versions to replace these to stiffen the frame for better handling.
