2012 4X4 Tacoma TRD exhaust install

yeah I know this is embarrasing, but I messed up one of my bolts while installing my TRD exhaust and was wondering if anyone on the forum could direct me to a place where I can buy the set to finish the job. Yeah I know I an get one at the dealer, but who else other than the dealer would I be able to get a new set from, online probably? I have another question, does the battery have to be disconnected for the sake of the computer resetting to the new install of the TRD exhaust? Thanks for everyone's contributions.

 

You dont need the battery disconnected to install the exhaust. As for the bolt, I would just go thru the dealer unless it is really far away.
