OK, I have another question for the treadheads out there - what are the differences between the M60A1 and the A3? How hard would it be to convert the kit for an A3 to an A1?
Thanks again for the assist!

Well, I'll just cover the external differences here and state some of them as they pertain to the M60A3TTS and the old M60A1 (not the M60A1 RISE/Passive used by the Marines in Desert Storm).
-The gun tube is different. The A3 had a thermal shroud around the tube to lessen gun tube droop. Plenty of aluminum tubes to replace the A3 tube with an A1 tube.
-The M60A3TTS (tank thermal sight) did not need a searchlight. The A1 had an IR searchlight. The M60A3TTS still had the searchlight mounts on it though.
-Tracks, the A3 used the newer style track with replaceable octagonal track pads. The A1 used the original style found on M48/M60/M88 that had a fixed chevron pattern. Late A1s used the late style as well.
-Aircleaners, the A3 used the newer style top loading aircleaner boxes and the early A1s used the older side loading style.
-A3 had a crosswind sensor mounted aft of the loader's hatch.
-A3 had smoke grenade launchers and storage boxes on the turret sides.
-A3 had an armored right side sight blister with a little door and padlock. The laser range finder emminated from this blister. An A1 would have an open blister for the coincidence range finder.
-Road wheels. During the A3's rein, the Army went to the smooth steel road wheel. It was still common to see the old finned aluminum road wheels intermixed with the steel ones as late as 1989. The A1 would have just had the finned aluminum road wheels (little strengthening fins added to the inner circumference of the road wheels).
That's basically it in a nutshell (externally). You can make an early M60A1 out of just about any M60A1 or M60A3 model on the market with just a little bit of backdating and some aftermarket items. Namely tracks and gun tube.
Only Tamiya's original M60A1 (solid OD one with white star) kit builds into the proper variant straight OOB. Its detailing is rather dated, but all the bits are there.
If you end up finding any M60 kit, contact me and I'll look at one of mine to see what you'd need to make it correct. I've probably got the proper tracks, gun tube and aircleaners in a parts box that I can send you.
Also, avoid the Trumpeter ones.
