Best tool to remove 1968 seat belt anchor bolt?

What is the best tool to remove anchor bolts for my 1968 Chevy impala? Or better what is the size socket?

From memory it is a one inch head on a 5/8-11x 1 inch. The factory used epoxy thread lock to hold the bolt in place so you will need a fair size handle on your ratchet or breaker bar to get them to turn initially. I have all sockets sizes from a 1/4 to 3/4 inch and a few inch sockets and Impact as ell as a breaker bar for stubborn bolts (such as the gland nut on the back of a VW engine) or working on rear ends that require a lot of torque. The longer the lever the less force you have to apply to generate a lot of torque, so if you have a half inch drive one inch socket add an adapter to allow you to turn the bolt with a 3/4 inch breaker bar with a 30 inch handle. Reduces the chance of your damaging the head of the bolt, rounding it off by applying any kind of a side load.

I don't know I never tried. I just twisted them out with a half inch breaker bar. It is a blue color so it may be Loc-Tite 242 if they had that stuff back in 1967.

Most seat belt bolt heads are 13/16. Use a 6 point socket, as the heads are shallow. Get under the car and clean the exposed threads with a wire brush and spray with a GOOD penetrant and let soak for a day.

If available, a 1/2" impact knocks the thread lock loose easily, but keep solid down pressure on the socket so it doesn't slip off.
