Shifter boot / Bezel Help.

I don't know? I have 2 here and just put one in Todds barracuda. I clearly remember my cars having that ring when I bought them in the 70's.. If you took the carpet out the boot stayed screwed to the floor with the bottom ring. These rings I have are for an A-body the boot is a different diameter then other bodies. They also fit over the rubber boot perfectly and when tightened seal the boot evenly to the floor. Otherwise what would hold the boot in place just the heads of the screws on the rubber at the corners.

You all need to think about it.

Unless I am shown another way to seal the boot to the floor and not rely on the chrome boot over the carpet , I'll keep using the lower ring that mine came with.

I believe some boots may have that ring built in. Mine don't. I wouldn't know if the after markets do , I never had to buy one yet. I still have originals
