In that case Frank, I'd recommend grabbing our latest SRPM and rebuild 
using rpmbuild but defining kversion for the kernel you are running. For 
example:

rpmbuild --rebuild --target=`uname -m` --define 'kversion 
3.10.0-693.el7.x86_64' nvidia-kmod-<version>.nosrc.rpm

Note: elrepo ships these as nosrc.rpm's so you will need to download the 
NVIDIA .run file separately and place it in your SOURCES directory. You 
will need the matching kernel-devel package installed for the kernel you 
are building against.

You should be able to use the matching nvidia-x11-drv package directly 
from elrepo without rebuilding it.
