Alright classic car folks, if you're working on a 1966-70 GM A-body restoration, these Inline Tube bucket seat brackets are exactly what you need. I just used them on my '68 Chevelle project, and the fit was spot-on. These are the real deal - they weld directly to your floor pan, and then your bucket seats bolt right onto them. The package comes with all four brackets you need to get the job done. The sheet metal quality is solid and they're made to OEM specifications, so you don't have to worry about modification or making things fit. They work with all the classic A-bodies - Chevelle, El Camino, GTO, Cutlass, Skylark, you name it. Installation was pretty straightforward if you've got welding experience, but if you're new to this, you might want to get some help. The brackets lined up perfectly with my floor pans and the seat mounting holes matched up exactly with my original seats. No drilling, no bending, no headaches. Seriously, if you're putting bucket seats back in your classic GM, these brackets will save you a ton of time and frustration. They're well-made, affordable, and most importantly - they fit right the first time!
