I need up pipe and pedestal o-ring part numbers ASAP

[EAD-fishing]

For the o-rings I went to the dfuser site and only found the o-rings for the pedestal to block. Can someone post up a part number or link for the o-rings that go in-between the turbo and pedestal. Is dfuser the only place to purchase these o-rings? I’d like to tackle this project this weekend.

For the up-pipe donuts I went to the carquest site and searched this part number, F17250, and it came back with nothing. Can someone please post up the correct part number for the gaskets that I need please? Also, would NAPA have these gaskets too or is CARQUEST the only auto parts store that carries them. Just asking because there aren’t any CARQUEST stores around here.

These are for a 2001 F250 4x4

Thanks!
