the mk2 panel i got had clips in it, so i just modifed the ones from the mk2 panel to fit into the mk1 panel and fitted it, not sure wer youd get them, i actually tried toyota and they couldnt get me any. halfords or motor factors might have clips that could do the job.
so do you have the mk1 glow panel and your trying to fit it to a mk2 bootlid? it should fit no bother mate
