Distributor lock nut

I guess you have a aftermarket exhaust manifold with the heater fins on top,if you can't see the nut or screw it might be difficult,try loosening the nut some times the screw will back out with it.
 
Some heater manifolds have a screw hole in them and some don't. The screw may back out along with the nut.
 
I would strongly suggest that a heater on your car in a Texas Summer would cause your distributor to be very hot.

Is it still on ?
