Looks like FP and GA is helping out JG for today, 7715 from Pond is on the B69, 7707 is on the B61 and 7188 from Grand is on the B9.
Also 7863 is on the B15 from FP (Possible Loan for this morning)
All the buses have GA Decals and are in service as of today. 7550-7551 was from MHV they also have GA Decals and was in service last week and is in service for today. 7531-7532 were Ex UP units and also have GA Decals and is in service so I don't think they are loans.
