Do I have a 1975 or 1976 RM125

[Dono113]

G'day all, pickup a bitsa of ebay, it was avertitised as a "RM125 with a TS125 engine". It turns it has a TS125 motor (engine Number-TS 125-103067 ) not sure of the year. Now the RM has a TS185 swingarm, shocks which have look like they are off a N model or later, the frame number is RM125-21109. Any help in the right direction would be great.
Cheers

You have a 1975 RM125M frame, if your engine has 4 short studs holding the barrel to the motor it will be a 1976 engine otherwise if it has 4 long studs through to the head then its a 73-75.
