So, just pick up the cheapest aluminum case or is that bad too?
Any recommended.. cheap case?

No much choice, but I have never bought one so there may be more available now.

FLM51500 is the 3905 diff cup, they do not seem to list a case. You can also get the cup with gears, FLM51000, that can take m3 thread screws which is a good idea. Still costs 32 bucks, but if you need new ring and pinion that along with 5382x will upgrade you to a solid new emaxx style diff

Heres a link to the cases that accept the 3905 diffs: http://www.ghhobby.com/proddetail.php?prod=2584

Looking at the various threads, they seem to lack the info that the 3905 maxx diffs are superior in design to the 3.3 and previous diffs. They have steel inserts to keep the spider/output gears in alignment. The al diff cups mainly help by not flexing, and the flm with the 3mm bolts and modded ring gears will handle more abuse than the stock 2.8?mm bolts and plastic cups will. The cups will not help the ring and pinion gears survive. Al cases will help them survive better, as the al does not flex like the plastic stock cases do, which alters the ring and pinion mesh.

So if I was to do this I would go with the flm cup with the modded ring gear, and the golden horizons diff cases. You can do the rear first as it takes more abuse, unless you jump alot, then the front can take some abuse during landings.

So about 25 shipped for one case and around 35 bucks for the flm cup/gears. And about 15 bucks for the 3905 specific internals. 75 bucks for 1 diff... Makes the lstd diffs cheaper, if you plan to do both (as the lst ratios are different to the traxxas ratio so you have to swap both).

So you all are starting to see why I went to the lst... Diffs are stout stock, no need to fool around like this.
