I would absolutely not recommend 35s with the stock Dana 35 axle in the rear, especially with 3.73 gearing. First, since you're asking the question you know you're looking for trouble. People run the combo, but the inevitable bang when your pinion gear explodes or your axle shaft pops is not the moment when you want to say man I wish I had upgraded my axle. A dead stop like that can cause a serious accident, especially at highway speeds. Here's a nice picture of what you can expect to deal with if you're lucky and don't hit anyone.

As well, with 35s there is a host of other considerations you need to make. The gearing at 3.73 isn't low enough to power the tires. Even at 4.11, I find myself downshifting often and rarely using 5th gear. The brakes need to be upgraded, and there aren't many options for those Dana 35 drum brakes. The steering components will also need to be upgraded because they wear out incredibly quickly. You're also going to wear your stock u-joints out and those will have to be addressed.
You'd be an idiot to do it without upgrading because you're just asking for trouble. Best case scenario you blow your pinion gear on a rural road. Mine blew going around a corner on a highway and luckily I could pull over to the side. Worst case scenario, you snap a shaft at 75mph and kill yourself or somebody else. Just do the 8.8 swap, replace your brakes, and factor in the necessities that go along with a tire upgrade.
