I just bought a donor Monte for my Monte and she came with a 7.5 rear with 410 gears "at least thats what i was told but I will figure that out for sure tomorrow". This rear is a peg leg right now so only one tire spins. I never really delt with rear ends enough to know what to do as far as upgrades go. I know the GN or Chevelle rears are where its at but i dont have that kind of cash right now so im just planning on beafing up this 7.5 rear if it really has 410 gears in it. I hear alot of people running mini spools "which my buddy just picked one up from Summit for about $90 and is getting it installed for $125" ...I also hear of people running lockers in these rears. Im on a budget but I need this rear to handle a hard launch with drag radials. She's not my daily driver just a street/strip car with manual steering/manual brakes, no sway bar, skinnys, cowl hood, mostly gutted and I'l be running a mild SBC350/TH350 trans which I will spray the balls off of til it blows. Not planning on spraying off the line unless I have rear to handle it, i would just be happy to be able to launch hard on drag radials and spray at the 60ft. What would you guys do with this rear, what are my options, best bang for the buck???...thanks in advance...I'l post progress soon "My Montes been sitting for 2 years and Im making moves to get her back and it feels good!
