Good things all around
So a couple problems here
My exhaust is falling apart. It's cracked everywhere and it seems to be letting air by the o2 sensor causing bad mileage so I ordered long tube headers to replace it and hopefully give better gas mileage so my question is do I need an o2 sensor in both, a y pipe or will the o2 sensor put in one with dual pipes work
The fuel pumps are still having the same issue except it barely works at all so I have a broadhead on a wire taking power from the fuse box to where the switch plugs in at and it works fine I just drove it 3000 miles round trip like that. I have power at the relay and as far as I can tell at the emergency shut off thing by the pedals but it's either lost at the switch or just before it but I'm hoping someone has experience with this and knows what might be wrong.
The key seems to be intermittently not working. It turns on every time but won't crank over sometimes. The neutral safety switch is jumpered so it's not that. I'm not really sure what's going on here but I've been starting it with a wrench.
And the big one here the rear axle has suddenly developed a bad leak at the pinion I've swapped one before but I know crush sleeves exist and I don't know which the 8.8 is. I have a 9 inch out of a 70s truck which unlike my current axle doesn't have half a million on it so I think that would just drop in right. Regardless I need to fix that seal anyway so can I pull the pinion off and swap it or does it need to come apart.

Not straightforward to use a 9" rear because it lacks the VSS. Besides that, 8.8" is a fine axle. If it has 500k miles it may have a lot of wear. Only way to know is pull it apart. Axle shafts leaking too? R&P ok? Might just need a set of bearings and be on your way.
