16 year old needs help with disc brake upgrade!!!!

Hey Guys,

Im currently a high school student that is restoring a 1971 dodge dart swinger. so i did allot of reading about the conversion out here but seems to me that everyone makes it sound way easier then it is. i ordered the exspensive poly graphite kit and what not. ended up trying to put it together with the kit(using the 73 center link) and that was an epic failure. then the pitman arm they sent has a larger shaft size then my steering gear box. so im back to 71 center link and 71 pitman and idler arm. will this work? whats the best way to align it all back up? i got the new tie rods screwed identical in lenght to the old ones and they are way off. as you can tell i dont have much automotive guidance, i am on my own with this car. and very frustrated at this point. then i figured going to power brakes would be easy instead i had to back pack all over here looking for a parts car for this little bracket to hold the booster on with. im piling up spare parts and doing allot more then what most posts said would be involved with this up grade. im wondering if my car is just the one messed up or is it me? this up grade takes allot especially doing it alone but i was wondering if theirs any tips or handy information available? and my next project is to tackle yukon axles in the rear. any advice or pics links or anything would be helpful concidering i have had the car torn apart for 3yrs now i would love to drive my senior yr to high school.

thanks - SAM
