We're all here to help each other

I know how you feel about doing two sets, I plan to swap out my 3.73's for some 4.10's eventually, but it doesn't hurt so bad since my front diff is injured already, and my G80 is inoperative, so actually the only "extra" expense from the repairs that I already need will be the rear gear set.

Check out Ron's Machining Service (sponsor here, they have a thread in the Sponsor Sales and Special Section with a discount for PT.net members IIRC), they have the best prices for gears and diffs that I've found anywhere.

using the tape measure they are 33 1/4 to be exact (worn) and were a little over 34 1/2 brand new, but my other 315's were around 35"

kinda funny how the different brand/manufaturers vary in sizes. My 33x12.50 KM2's off my jeep were 34.5 new, my procomp 33x12.50's were 32.9 new

x10000, and I would pick 5.13s. And I have still yet to see any cam make more TQ down low then just a stock cam. I just re geared my truck from 3.42s to 4.56s only on 33's, and the difference is amazing. Don't fear the gear, mechanical advantage is the best. BTW front and rear, with install kits, was only 399 shipped from our sponsor rons machining service, then got them installed for 650.
