Quite easy mate really and cheers for the comments, i got two stainless tubes made for each side then cut two holes per side, slid the tubes into the holes then put the lights in from behind and secured them in .I then fibreglassed and fillered each side, a very good coating of spray filler then two pack primer then top coat.
The only thing i would do different if i was doing it again, i would make it so i did not have to slightly trim the rear panel to get them in . A lesson learned i reckon.
They dont weigh too much either which is good.
