Gauge cluster screws?

[terrible one]

Before I go to the hardware store and buy a huge lot of random screws, etc. to try out, does anyone know the size, or approximate size of the screws that hold the gauge cluster into the dash frame?

Also, what about the size for the bolts that mount the seat bracket to the floor? I take it the original tracks had studs, but I will be using nuts and bolts. Does anyone know what size fills/ fits the hole in the floor?

Thanks!

I posted pictures somewhere of the gauge screws on this site for the wood dash.  As for the seat bolts, I think mine were 3/8 course thread.  Kinda long though originally.

The original seat tracks had studs like you said. they where 5/16, but if you are useing aftermarket seats anyway you may be able to get away with 3/8 bolts . The holes are fairly big in the floor.
