Interesting thought- the tooth counts are the same -43/13- depending on which exact version you get, lst2 for example. Im also gonna say the bearings must be the same inside diameters at least -both diffs will accept the RC-M output shafts and they both have an 8mm bore input shaft-...

Im sure you can look up which size bearings they each take, but I do reckon that with a little shiming they may well fit perfectly. Only down side is that the UE cases are $60 each, but it still works out at half the price of full blown 6 spider models costing $260 for a pair...
