Sounds like all new bag $$$$, your state may require new bags, some do some don't. . Take it to a shop of your choice as a cash job. They can't force you to repair anywhere just like the other gentleman posted.
Use the extra money for Xmas gifts.
Use aftermarket capa certified parts. Keep in mind the mileage on this truck. If it goes another 2 years that's still not enough in my book to buy oem parts for a light nose shot.
Although I do agree with you that with the mileage sometimes aftermarket parts are good enough, I say go with OEM for most of it. Take it from someone who has put hundreds of these GMs together after collision, the aftermarket fenders, bumpers, grills, and lights are mostly junk. Not saying that you cant just replace one thing aftermarket and it will look alright, but when you start doing the whole front end, you are better off with OEM 100% of the time.
Actually, since it is a GMC, you cant even use the capa grill. The aftermarket companies cant stamp out the GMC logo where the emblem clips in to. So instead the part that it clips onto is a black square, so when you clip your GMC logo in, the grill isnt cut around the actual letters. (not sure if I explained that good enough)
