How do I get axles out of differential

Cant seem to get my hands on a set of factory injectors. What after market injectors work well on a stock setup? Not looking for performance gains, mine are just leaky. Also what cc are the stock injectors? Thanks

Car has since been running lean until warmup, also lean for a short period of time on hot start when restarting. Is this open/ close loop switch? ohm tested ecu coolant temp, within range temp sender for dash in range air conditioner temp sender shows some crazy resistance, not sure if applicable to air fuel at warm up though   literally like a switch is flipped once it reaches certain temp scares me to drive at like 18 aft and to even let it idle like that   timing is bumped up to about 13-14.

looking for an uncracked exhaust manifold shipped to 34224, thanks
