BB 68 BSA Threaded, Listed as 1799 USD

Two Numbers: The wheelbase and chainstay length have two numbers, because the frame has some way of varying it. I think I remember there is some sort of adjustable dropout plate.

ShiftModel: Shimano Sora

Stem: Salsa Guide, Salsa Cowchipper Salsa Guide comes in 80,100.120,130 length

BrakeMount:

Derailleur Replacement: Jerremy says: A replacement derailleur will be no problem. Sora is 9 speed, and 9 speed road and mountain are generally interchangeable. Running a Sora R3000 GS rear derailleur (for road cassettes up to 30t,) or an Alivio M4000 SGS (for mountain cassettes up to 36t,) will be the best replacement choice.

My Interpretation: The Sora build may not come with exactly a Sora R3000 GS, but a Sora R3000 GS would be a good replacement.
