they have diffrent diammeter springs in a 240, so people that put em in 1200s and 120ys cut the spring cup off and weld on a smaller one, usually they thread the strut at the same time to give adjustable height aswell, but unless it has the diffrent spring cup size it wont work for your 120y, and im not sure about the tops, they would also need to be modified 120y ones i guess
