This is a concern for basically all rubbery things under the hood: vacuum lines, fuel lines, water hoses fan belts (well those don't leak).
Last but not least, take all brakes apart and replace the worn parts.
Dammit, I was gonna say that
I'll X2 that. Start replacing all the hoses under the hood. Replace all the fluids, including rear end oil, and new grease in the nipples.
get some carb cleaner, spray it slowly into the carb, so you don't stall it right away, but spray it bit-by-bit until you get near like a 1/4 end of the can, then give it to her to stall it. then you're gonna be letting it sit for like at least 6 hours. Make sure it's at operating temp first.
new plugs, wires, coil (if you can do the HEI swap-over, that will be a big help)
Give your brakes a total shakedown. check, clean, or replace. I redid mine except for the master cylinder. all new fluid, wheel cylinders, spring kit, drums, pads and shoes, etc. all of it was cheap, except for the drums. If you can't find the replacement drums (if you need them) there's a common jeep drum replacement that will fit.
