does anyone know where i can get a replacement airbox? i have a crack in the lid and dont want it to get worse and bring unfiltered air to the engine so i want to replace it.

 

Have you tried sealing it up with some 2 part epoxy? That's what I would do, but you could always see what is available at your local junkyard. I'm sure it wouldn't be more than $10 for the whole box...

 

eBay would be your third best option after attempting to repair, then boneyard. If I remember correctly from photoediting rims onto your truck, you have a pre-'98? This was the only one I could find. Like Kyle said, the local junkyard would be your best bet if you can't repair it on your own.
