so i searched and didn't really find an answer.. can i get donut gaskets for the DP at Autozone or some shop like that?

and if i have a bolted DP can i weld it in?

i'm hopefully putting it in tomorrow

Here are the gasket part#s for a bolt in downpipe:
Front Gasket: 31605 (Walker Exhaust)
Rear Gasket: 31532 (Walker Exhaust)

A NAPA parts store would probably have them, that's where I bought mine.

what about bolts in case they break? i'm putting pb blaster on them so hopefully not but would they have them?

Ace Hardware.

Napa sells an Exhaust Manifold Stud & Nut Kit: BK 6003233 Your bolts will probably snap (mine did), so be prepared to drill them out...

uh oh, im getting ready to do mine, i guess ill just take it easy, BTW i got my gaskets from ZZP for like 20$ shipped, came today , so here i go with my clogged cat !!

When I dropped my DP to put the stock back in, the bolts were fairly stripped, and the nuts would not go on far enough to tighten up. LUCKILY I have a Tap and Die set, and was able to salvage the bolts, and then just bought new nuts and it was fine.

I DID try to remove the old studs, but without a torch to heat them up, and not wanting to drop the rear mani for better access ( was laying on my back doing the work with the car on jack stands) I was lucky to be able to correct the threads.

not to jack the thread, but my bolts are prettyyyy stuck on there, ive gotten no further when i left, and it sucks

WD-40?

When you replace the bolts spring for stainless bolts and always use some anti-seize.
