Stuck countershaft nut

Well, I've just about reached my frustration point, and I'm about to call in the big guns, which sometimes gets me in trouble. So, before I do that I wanted to see if there's anything else I should be trying... Here's the deal:

I'm trying to replace the oil seal on the countershaft of a '40 M. I've dropped the lift-all pump (in fact, the tractor is split so I've got complete access through the clutch housing), but I can't seem to get the countershaft nut off. I've engaged two gears to freeze the tranny, and I've given it everything I've got with a pipe wrench and extra leverage. I've pulled hard enough with the pipe wrench that I've scored the nut with the wrench's teeth. It's not budging...

I made up a tool by welding a 2-inch piece of 1/2 square bar onto a big ol' inch-and-quarter nut. I can now put this thingey into the countershaft nut directly and then turn the tool with a socket. I'm about to hit with with an impact wrench to see if that will break it loose, but there's a little voice in the back of my head saying CAUTION!

I know these trannies were built to take a beating, but how much risk am I taking to breaking the two gears I've got engaged? I could try bracing the countershaft with wood blocking, but I might end up driving the blocking in so hard that I can't get it out...ah...just answered my own question: I can drive the blocking out when I reverse the process and drive the nut back on.

Any thoughts or words of wisdom?

Thanks,

- David
