<font face="Comic Sans MS">You'll probably want to pull one and head to the hardware store. Might want the sort that have an allen head in 'em. That way it'll still fit down into the hole and you have a way to tighten it down. [img]/wwwthreads_images/icons/crazy.gif[/img]
I think that response by swamper was simply stupid and intended to be completely ignored.</font>
Lol, to late swamper, saw what you wrote! I check this board every 15 seconds on the dot and you can't delete a post fast enough for me not to see it!!!!! Yeah, I know, I have no life[img]/wwwthreads_images/icons/frown.gif[/img], but I have a Big Willy![img]/wwwthreads_images/icons/laugh.gif[/img][img]/wwwthreads_images/icons/smile.gif[/img] Ok, I'm banned...
Anyway, I have the springs for the camaro in the garage and they have a 7/16" pin, but I'm not sure if that will be the same as the trucks.
To make it easier, get a grade 8 allen head cap screw. I think that a 3/8" bolt is the right size. Get ones that are too long but have enough threads to pull the spring pack together. Then simply use a hacksaw and cut the end of the bolt off. This way you will have the perfect length bolt.
