tie rod

Quick question fellas, do I have to change the pedal according power or manual brakes or is it changed because its going from drum to disc? I currently have a power booster pedal assembly and I'm curious to if I have to change anything involving my pedals. I'm asking because I'm on the cusp...

I remember there being a complete tie rod kit on Ebay that I can't find anymore. Does anyone else know where to get a good deal on the entire tie rod system?

I have a 73 mercury cougar xr7. im replacing the front suspension on both sides and was told there is a special way to do it or i could get hurt fromt he shock or something? Any tips or advice? id love to have a step by step if anyone would be willing
