5th gear went Pop

They can't be that bad, do they?
I like to believe the reason gearbox failed on that mileage might be 'cos the previous owner has been bashing and thrashing it around.
For example, mine doesn't look that good in terms of other parts of the vehicle, like the engine, suspension, diffs, etc 'cos all of them gave me lot of crap trouble, but not the transmission. I doubt the tranny has already been through any work on it.

You can source RB30 boxes cheaply, but might be necessary to take a chance with them, which is something you probably don't wanna do now 'cos you've already got burnt by a used one.

Some have posted that they absolutely thrash their RB30s and they're getting high mileage out of the gear train. The problem is that the gearbox internals are basically designed for road vehicles.

There was one wrecker ( can't remember their name) in the Eastern burbs that was splitting a number of boxes and making one good unit out of them. He was giving a 3 month warranty, but was asking top dollar.
