It will not fit a 75. Kaymar makes a bar for the 75 and that is the one I used on my 74. The wings are much shorter and do not have forward brackets. Also the brackets that go forward and bolt to the bottom of the frame are longer. Those have to be cut off to put it on a 70, 71 ,73, 74.View attachment 1929177
Hi Dan I hate to disagree with you but these will fit on a 75/78 with a few minor mods on the brackets. I have just bought 3 of these and will use one on my troopy in the US, another on a troopy in Belgium and the third one will be for sale

Here are a few pics of a company in Europe that mounted a 76 bumper on a 78.
