I've researched a few threads and still have questions.

I'm putting in shoulder belts in my 69 and I dont have the original hardware.
The new kit comes with 1/2 course thread bolts for the floor and 7/16 fine thread bolts for the pillar mount.

None of them seam to thread in and I don't want to strip them.

I've read that they are interferance threads but I don't understand that.

What am I missing?

Thanks
