Your mileage is on par with the originals with much smaller 4 cyl engines. I like the stainless marine senders for about $20 on ebay. You match the ohms sweep range and direction to the gauge you will use and the length to the tank depth. Much better than the swingarm universal senders that corrode quickly.
Good heims are not cheap. I’d look at truck tierod ends to replace them, reaming rod, extra thick wall pipe or plate for the taper seat. To eliminate bind, you could fit an tunnel A arm around the diff and use single outboard links like the 99 and older tracker/sidekick.
The 224210 seal is about $5 each free ship on ebay.
Since you are eventually going ms efi, you could go ahead and fit a yard pull EDIS system, cut and shut the dizzy just above the retainer slot, leaving the bottom to drive the oil pump off the camshaft, then turn the carb around to eliminate the spacer and the rear bowl won’t hit the dist cap.
If you were staying carb I’d suggest a weber solex type 34 or 38 two barrel or a conservative better low rpm response 32x36 progressive. These keep the barrels in the best location over the lower intake ports yet bring the linkage to the side to clear the upper intake. They are common on straight and vee sixes and often an upgrade on larger six jeeps. May be able to find used to rebuild in a yard or new for about $100 free ship on ebay. Holley made great progressive carbs too based on the normal two barrel body but the linkage was turned 90 deg since there are two throttle shafts versus one. Rare carb these days but mine worked great on a chevy 2.8l.
Pricey used 32/36 dgav but showing design and filter:
