'85 CJ7 gear shifter knob thread size?

Anybody know for sure the thread size of the gear shifter knob on an '85 CJ7 with a T5 tranny? I can't seem to get a definitive answer off the net. I think that it's 3/8-16...I think. But some sites are saying that it's 3/8-24. From what I've read, the '80-86s are the same, and the thread size is the same for the T5/T4/T176/T177 and Dana 300s... but what is that thread size?
If anybody knows without a doubt, I'd appreciate hearing from you.

I have an 82 cj7 and I ordered a 3/8-16 from the vendor that sells pool ball knobs here and it did not fit my T4. It doesn't seem to be wide enough or the threading is different because it is not catching.

Nobody's jumping all over this one I see. Like I said before, I couldn't find anything conclusive on the net, even from vendors. One guy would tell me that it's 100% this size, the next would tell me that it's 100% that size. I ended up getting a universal fit one, which looks awesome, but was a piece of junk. The knob is great looking, but that's about it. It came with different size sleeves and 3 teeny weeny little allen head bolts that are supposed to hold it securely to the shaft...yeah, right. The first time that I would have shifted her into 2nd the knob would have ended up through the windshield of the guy behind me. Anyway, I modified it and it's super tight now. I think that the only way to know for sure what will fit on your shifter is to go down to the good old hardware store, buy a couple of nuts..say one 3/8x16 and one 3/8x24 which are your two likely candidates. Keep track of which is which, and the one that screws onto your shifter will give you your answer. But from what you said, it sounds like you need a 3/8X24.

I spoke to one guy who's been selling shifter knobs since forever, and he told me that Jeep CJs varied from year to year, between 3/8X16 and 3/8X24 thread patterns. He even said that they often varied within the same model year and that it's impossible to say which one you have without looking at it or trying a nut on it.
