Seat Bolt
« on: September 27, 2023, 16:13:51 »
Good afternoon,

Does anyone have a source for the bolts that secure the front of the seat rails to the frame of the car? I have tried to purchase bolts from a local nut and bolt shop, but none of them are threading easily, so I am trying to see if the original bolts are available or if anyone has any advice on a suitable replacement, I am certainly open to any suggestions.

Thanks, in advance, for your help.

If they don't thread easy, I would run a tap through to clean the threads prior to installation. I lost my original bolts during restauration and (temporarily) used simple socket head bolts to fasten the rails to the frame.

The normal M8 hex head with a SW of 13mm will interfere with the rails. Either use (as shown) special  SW 10mm , M8 hex bolts or socket heads.
