After finishing my tranny swap last night (9pm) was getting kinda dark. We threw the h-pipe on and bolted it up quickly. Noticed after about an hour i had a pretty bad exaust leak, so i took it home and parked it for the night. Went to look at it this morning and im missing 3 outta the 4 nuts that bolt the h-pipe onto the headers, the studs are still in (thank god) so i need to find new nuts, where can i find that high of grade nut so they dont rust to hell after a few months??

 

lowes/homedepot.... grade 8 bolts dude.
