what seat belt assembly fit a 1994 sierra 1500 extended cab that doesnt have holes for seat belts

Nosmo- don't mess around with seat belts, they are there to save your life and to do that they must work correctly,100% the factory spends a lot of time and money on engineering and actual crash tests to make sure these things WORK correctly- is there anyone not bothered by seat belts? they annoy the heck outta me- but I wear them- some cars fit me better than others- think of the poor women who have the shoulder belts pressing down between their breasts- how comfortable can that be?! These automobiles we know and love are not just giant playthings- There were over 35,000 highway fatalities in the United States last year. 35,000 dead people thanks to our beloved motor vehicles. Just a statistic to you and me- but a very grim reality for the victims, their friends and families- do the seat belts RIGHT
