newbie here with 72 blazer

[WarMonger]

Hello everyone on the blazer side. I just picked up this 72 blazer and have a few questions for you guys. I have a 70 C20 so I'm not completely retarded, but you never know what I will come up with.

So... I got this blazer and now my plans are to to convert it to 2WD and put it on the ground. I'm not going to bag it, but just use springs to get there.

1st one: I found a front clip/end for the blazer, so the rear is what I need info on. should I keep the rear axle I have, or should that go with all the suspension?

2nd: rear has leaf springs, so I was leaning more toward coils with trailing arms, what do you guys think?

3rd: should I sell front diff, 4 speed trans, transfer case all together or separate them?

Thanks guys. Here are some pics. I know when you post, you have to have pics.
