What I figured- was leaning toward the splined ones as that's what was in the last truck, now how to put'em in? Do ya drill a smaller hole where ya want the nut and drive the splined nut in with a hammer? Just found something I like a little better...

 

Speaking of splined nuts, and for that matter studs, where can i get a couple to put in my firewall to mount my aux battery relay??

Also, on the bedliner topic i think i am going to get a kit of the tintable raptor bedliner and see how it looks in the bed, tinted with the purple my truck is painted....

 

All I've seen is online; Home Depot does carry a type of expansion insert, but I'm still guessing that you'd need something to drive it into the metal like a pneumatic tool of some sort......

 

Any long term updates on the Raptor in the bed?

Thanks!
