It got done at Grand Ave most likely, unless it was an accident repair. Zerega gets the 63xx's, 64xx's, artics, MCI's, and all of the TA/OA NG's for program and overhaul work. Grand Avenue gets all of the higher numbered OG hybrids, all of the CNG buses, a large majority of the engine rebuilds, majority of the small unit rebuilds, and a majority of the fabrication work. Work on non scheduled and accident buses get about a 60/40 split between the 2 with the larger portion going to grand ave.
