Vulcan's XM573 and XM606

Does anyone know what the current status of these two are? 573 was recently moved indoors and it looked like she was missing her engines?
XM606 on the other hand looks in good overall condition but has a deflated nose gear strut making her assume a nose down attitude. Online there are pics with comments about her being structurally damaged causing the nose to droop.. Had a chuckle at that one.
Any updated info would be great!
