510-1***** is 1976 YZ400C
510-2***** is 1976 IT400C

The YZ-C (510-1*****) and IT-C (510-2*****) frames are identical, but the MX-B (510-0****) frame is very slightly different.

All geometry etc is the same, but the MX-B only has one muffler mounting point on the rear frame loop, YZ-C and IT-C have two mounting points.

Then it's an IT400C motor - same as YZ-C but wide ratio gearbox and lighting coil.
