Instead of buying screw kits,
which are expensive for what you get, for a particular truck, why not just put together a list of the size screws that you will need and order in quantity from
www.microfastener.com? They have about the cheapest prices around. Plus, doing it this way, you'll always have some extras, just in case you loose some. And ALWAYS use good quality allen wrenches; they aren't that much more than the cheapies.
