If you plan on doing the gear change yourself then do a tech article about it with pics. I have never done a set of gears. I have helped in small parts of it but have never seen a set done from start to finish. I know that it requires special tools and patience with shims and bearing tightness' but thats the extent of my knowledge.
Let us all learn from your gear change.

Like Kyle said as long as you still have the D35 axle or the Chryco 8.25 then the 4.56 will be your limit.
I am running 4.5 now on 35s and it does just fine! 4.88 are desirable but not worth the change since there's not a huge difference between 4.56 and 4.88.

Do you hear banjos?
I forget about the fact that I live at 6800' of elevation. You guys at or near sea level MUST have quite a bit more power than I do up here! I know that my DD is a hot rod when I drive it to OK to visit friends and family. It may be ok w/ 4.56s at a lower elevation, due to the fact that you guys have a lot more oxygen down there,....wait.... maybe that's why I don't remeber my current elevation, oxygen deprivation!!!LOL.... Hope whatever you choose works out for you!!

I personally will not be doing the gears, I'll be there to give a helping hand and watch but thats about it
runnin the 8.8 in the rear, i think i'll go ahead and try 4.56s.

We got into a big discussion about this once at a club meeting. 4.88's are the way to go if you can. They work in a Dana 30 but you will not get the ideal contact between the ring gear and the pinion. The ring gear is so small in a Dana 30 that when you start taking teeth off it to achieve a lower ratio you don't leave a whole lot for the pinion to engage. They will work and many people will never have a problem until you really starting pushing it, larger tires, more HP.
