As promised a few additional updates....
For the rear axle I had been debating spending the money and putting in a new 4 link. In the end I decided to run with the original leaf spring setup. I ordered a CPP Rear End Conversion Kit. I had a rear axle that the axle code shows coming from a late 60's early 70's Camaro or Nova. I'm thinking I might need to take out a couple of the leafs - to drop the height a little. I will need to see how it sits. I'm also considering doing the shackle flip - but think it might give me more of a drop then what I really want....

Last weekend I installed the new 20GAL fuel cell. I needed to move the rear cross member back to make room - but there is plenty of space. I was mostly concerned about the clearance from the ground- but I'm happy with how it seems to fits.
I also picked up a Power Brake setup kit - I did a test fit to make sure it clears the transmission cross-member mount. Looks like everything will clear. My plans for the coming weekend is to run the new fuel and brake lines!
