I have a 99 Silverado ext. cab. The issue i am having is that the front seats slid a little when i stop. It is not much like a 1/4 of on inch, but it is really pissing me off. I checked the tracks and noting is wrong with them, i also checked the bolts they seem to be tight. I was thinking of taking them out to look at them more, but it has a wierd shape for the bolts what tool do i need to use on this. Any suggestion would be great. Thanks for the help.
