Will a Jeep Dana 30 gear carrier work in a Bronco Dana 30?

I'm looking to upgrade to 4.10 gearing from my stock 3.50's in my pavement queen dana 30. The carrier break on a Dana 30 is 3.73 so I need the series 4 carrier.
Will a Dana 30 series 4 carrier from a 1989 Jeep YJ work in the Bronco diff? I think the Jeep carrier runs reverse cut gears and may be a high pinion, so can I assume that I'll need to get a new 4.10 ring and pinion? How about the spider gears? Are the Jeep ones usable in the Bronco?
I know everyone recommends the D44 upgrade but for my intended use I don't think I'll need it.

Yes. That is the old stuff still. The high pinion means the gears won't work. But the carrier is still the same.
