Seatbelt install help!

[theautomatics]

I've got a 68' mustang coupe. With 500hp and no seatbelts I figure i need at least a 3 point seatbelt. Can this be installed into the body? Pillar wall? do I have to get race bucket seats a roll bar?

I installed 3 point seat belts in my '65, but I had to add metal into the roof rail area for a strong anchor point.

I thought the '68's already had the beefed up metal and hole there to bolt the shoulder anchor point. It'd be best if you could look at another '68 with the headliner removed to get some measurements.

I'm sure someone with a '68 will chime in...
