is it an aftermarket seat? Im pretty sure the eg rails are the same as the DC2, so one of the rear holes will not line up and will need drilling out to fit.
yeah man 3 of the holes will line up. if its the drivers seat the rear left hand one may need a small bit of metal welded on then drilled out. easily done, iv seen people run them with 3 bolts but i wouldnt for safety reasons
im running them just on 3 bolts. seats defo not going anywhere soon. so its still half safe. i cudnt be arsed drilling and re tapping new holes
