8.75 and 8.25 ready to go in (almost)

Both of these look amazing, I am looking into getting a 8.25 for my Dart in the future (once funds and fiance allow) What do you think is the ballpark price for one like yours for either building it yourself or buying it finished? I don't mind drums in the rear but I am also a fan of going to the junkyard and seeing what new stuff can work with my old stuff, especially if it came off a Jeep

I bought a Sure Grip 8.25 out of an F-body from a guy on Craigslist, cost me $300 to buy, I was in it for less than $1000 by the time I got it installed in the car (spring perch relocation, brakes, wheels/tires) Overall it was well worth the investment, better traction, I got more aggressive gears, and more beefiness than the 7.25 I started with
