If you want fast, then Rovers North can't be beat for anything in stock.
Cheap and reasonable fast, LR Direct. But make sure to get items that they say are in stock. I had a few items that were not and took 2 weeks to get. Not fun.
If I understand, you want to go back to the side pickup version, aka , external pump version. If so you want NRC7570. It comes with a seal and locking ring for the sender. The "cradle" was a PITA to get on so I did not put it on mine. I will probably get an aftermarket skidplate instead. The sender you want is PRC8463. The filler tube should be NTC2337, but someone will have to confirm, I ended up not needing it.
For the sway bars, I ended up getting the entire ball joint because it was only like $8. It had the bushings already pressed in and had the castle nut and locking pin. NTC1888 should do all 4. Front bar to frame rubber should be
NTC6828. Rear should be NTC7394.
Edit; be careful of the minimum qty with LRDirect. With a given item, some brands will be super cheap, like $0.17, but you have to order 30 of them. Another brand might be $0.40, but you can order less.
