Do you think I could keep the stock front end with 35s and 7" of lift?

You mean install an IFS on your 2WD truck with 7" of lift? I think that would be a ton of work. It would actually be easier to swap frames. An SAS is much more practical, IMO.

No, I mean can I sas it and keep the stock front bumper?

Sure, no problem. I ran my stock bumper for a while before I built the one I have now.

Ok thanks.

No problem. Good luck.

Oh and will rack and pinion work with sas?

Nope. Or at least not without a lot of work and custom fabrication. Fortunately, it's not that difficult to install a steering box (I think older F-250 trucks are popular donors.

I was lucky that mine came with a steering box instead of rack and pinion.

Do you know what axles are the right length? I don't really feel like narrowing a axle.

My wheels have like 5" of backspacing, so the wide track J10 axle was perfect. So was the full-width Chevy rear axle. For wheels with less backspacing, the narrow-track Wagoneer axles work well. I've also heard of people using axles from full-sized Broncos (before they went to the TTB, obviously). In fact, using the whole radius arm setup from the Bronco is one of the easiest and cheapest ways to do an SAS.
