Install your self a belly plate to protect that alloy pan from pancaking on launch. McMasters is your number one local resource for the aluminum and some limited Titanium hardware. Look no further than 2024-T4 aluminum bolts. Even some of the low grade material is okay, but can not take the little extra tightening torque that the 2024's can. You are only carrying about 45-50 pounds of fenders with about 8-10 bolts, so not so crucial, but for safe keeping, get the 2024-T's. Get yourself some anti-seize to smear on the bolt threads before you install them. Using the originals, make a list of their lengths and thread size to make sure you have the right size bolts in the mail. you can even cheat the length by a few 16ths to save a few more ounces. I can look at my notes and get back to you before I leave town so that you order the right stuff. It would pretty much be the same for all other car models in the Mopar camp, so keep a peep guys for future reference.
