I have a sway bar on my car. I am sure it's a 77 GM unit. It was installed back in 1984. The rear control arms had a insert welded in to install the bar. I would like to correct it to the factory style mounting bracket. I found part #10191120 from GM direct. Can one of you guy's confirm these brackets are the correct ones for my 1977 supreme. Trying to make it all OEM and NICE! the welds look like crap.
