If you use the transfercase drop you will be okay without a SYE. I rolled without a SYE and CV driveshaft until I went SOA.

Like Crafty said, as long as you use the t-case drop kit you'll be alright.
The 4.2L should be able to turn 33's. What gears are you running in it now? I'd run at least 3.73 or numerically higher gears. If you go SYE and CV, you'll have to measure for drive line length and you will need a new shaft if you go SYE. Drive line length will vary depending on each individual rig so your on your own on that one.
Here is a great drive line measuring guide from Tom Woods.

LOL I am sticking with 33's. I am getting full tuck with the amount of flex I am getting. If I go to 35's I would need a Body Lift, regear again and fix my weakpoint--stock front axle. I am very happy with my current setup.

I need to regear my d30 and then see how far I can shove my 35's in. When I had the 38's I couldn't quite get the rear tires all up in there. The fronts though, I had them almost touching the bottom lip of the hood.

You runnin 3.73 or 4.10?

4:10'S with about 17 MPG and can cruise the interstate at 85 MPH with no problems. Another reason not to go higher--I am only 5'4

Awww. 5'4"......Just get a rope ladder like some helicopters have and bolt it to the seat bracket. I've been sayin I am going to do that for years.

I can do 85 too with 3.73 and 35's but @ 355 cubic inches there ain't no way I'm getting 17mpg.
You got more pics of your rig somewheres?
