Now the discution about a 79 tray fits a 75 is dead.... I did change mine to day. I did cut 8cm of the floor and sidewalls in the front of the tray. You have to cut of 8 cm of the front support for the bolts thats connects the frame and tray. The easy way to do it is to drill out the spot welding and cut it and weld it back on place. The six other bolt did fit perfect.....spot on....
