Those images posted fine. Your MKI* tray looks good enough to have come off the JD in the background. Just needs some two-tone green and yellow paint.
Dave, could you simply strip off the unwanted bits, trim the tray to length, fill in the remaining slider openings? Reproduce a MKII* forward leg and rear support to match the original version? Reverse the hold down rods and good to go!
It would save Richie paying the postage to the UK.
