interchangeable parts for first gen questions

So the run down. I am in the process of installing a total chaos long travel kit on my 04Tacoma tacoma. King shocks, glassworks 6.5 fenders. The kit itself is going smooth but I got stuck at the lower a arm. The alignment bolt is rusted into the arm. The bolt itself is out but it is the alignment rod( whatever it is called). The best descriptionto i have for the part is, the a arm has a metal bushing inside it. The peice that goes in through the frame has the aligment circle on the out side and a fitting on the other, then a bolt goes through and screws into a nut on the other alignment nut. I slapped it around with a hammer and hit it with penetrating fluid. As of right now i want to just cut it out and replace it. The question is would a 95 alignment rod work in my 2004 Tacoma or what are the limitations of the parts that are interchangeable? Sorry for the random words and spellings i am doing this through mobile.
