I would like to re-do the seat cover on my 99 XPL & found that the seat straps are not held in place like my 98. The 98 had a hex bolt on either end of the strap, so it was easy to take off. The 99 appears to have some sort of stud that is threaded into a plate on the ends of the strap? Do I drill them out?

This simple job has me stumped.
