extending wheel base

[CheapThrillB2]

welli am tearing down the susp on the B2, and i am thinking of extending the wheelbase. I was thinking in the front. But i want to retain coils and i currently rn a D44 SAS on it. I was also thinking of extending the rear, but i am worried about the rear 1/4 interefernce with the tires. What is everyones ideas on coil relocation, and steering geometry. As well as what are some ideas in the rear retaining leaf springs.

There are some things to consider. Get a zero rate leaf. Will allow you to push your axle back at different intervals depending on what you want. The front is easy. Move your lower bucket back at the axle. I am currently at 100 inches exactly. There is no way you can do it without trimming though. I am running a short high steer arm at the axle and a longer pitman arm though. I am going to swap them both out though for something a little different.

I agree with the Zero-rate add a leaf. I wouldn't go more than 2" with it. My truck sits a 97" Wb with the front pushed 1" forward and the back 2".

The the extended shackle I am only about 1 3/4" in the back. The rest is in the front. I had my front pushed another inch forward from where it is now but I didn't like how the steering was going to be so I pulled it back. I had to trim a LOT off the front of my fenders up towards the bumper.
