Other then Mr Lloyd G. Reynolds and some model kits I can't find a single reference to an M48A2 in the USMC. Tho it's possible some of the M48A1s may have actually been M48A2s as they're essentially identical:

"This version, first accepted in 1956, first had and improved powerpack and transmission (a fuel-injected version of Continental’s V-12)
Second, a redesigned rear plate with exhaust louvres, and side hull intake grilles surrounded a solid center area overtop of the exhaust tunnel, greatly improving the infared signature. The more compact design inside the engine compartment allowed to fit bigger capacity fuel tanks, for 335 US gallons (1270L), giving an approximative range of 160 miles or 260 km. Moreover the A2 had a an improved turret control, and relocated engine\’s air cleaners for better access and maintenance. The suspensions also were modified, with a modified compensating idler wheel attachment, double bump spring on the first road wheel arm, and friction snubbers instead of the hydraulic shock absorbers. The second and fourth track return rollers were deleted. The driver\’s steering wheel was enlarged, and the transmission shifter was relocated to the floor on the driver\’s right. It had also a modified personnel heater exhaust pipe, an improved turret control system, and flattened fenders."
