Got ready to try and mount the Go Wing on our 71 Cuda and it seems that we have two 1970 trunk lids. So the brackets that go under deck lid are for a 71 and don't fit the 1970 cut outs. So it is as simple as getting the underneath brackets for a 70 and you are good to go, looks like the wing position is slightly different from 70 to 71. Or is is possible to fill the 70 cut outs and put in the correct 71 cut outs, or is the ribbing just totaly different between the two years?
