Ring gear identity or different diffs?

[ithrowstones]

I stripped the ring & pinion gear out of a traxxas Tmaxx 2.5, rear end is spooled. Bought a new set, (part # TRA5379R) to replace it at the hobby shop today. Turns out the new one (black gear) has a taller "collar" (I'll say anyways) which won't allow the dog bone coupler for axle to accept the grub screw. I have no idea who or what brand was in here to begin with as i am not the one who originally spooled it.
If any of you knowledgeable gurus know your ring gears, can you help me find one that matches?
ORRRRRR does anyone know if the Brushless emaxx or revo 3.3 diffs/housings are a direct fit in the tmaxx's bulkhead, if so, are they better than what's in the t-maxx? This is an electric converted t-maxx with much juice, sip-sip hooray! (brushless emaxx trans)
Already has steel driveshafts & axles, I believe to be M.I.P brand.
Sorry for low quality pics, i did my best
Thanks.

The TMaxx 2.5 classic uses the 4981 ring gear in both front and rear diffs

The 5379R set is for the 1/10th scale 4x4s, like the Slash, Rustler, etc.
