mini tub....74 dart !! what's involved ??

Thanks guys....... To the tire size question , I'm not real sure but they're huge and they were rubbing. Kinda just got in the middle of this thing last night. What his question was ...he wanted to know the different between mini tub and just tub. Which I didn't really have a good answer but figured that the full tub was when you cut the rear end down and all that good stuff. That's when he said he didn't want to get into all that, I'm sure he'll get the kits that he needs and move the springs in. Like I said before sorry about some of the dumb questions....I love my mopars but this stuff is all new to me and I figure if you're going to do this stuff , make sure it's done right the first time.
