77cruiser77, Yes, if you could put up some photos that would be great. I did try RADD but he couldn't help. Building it is probably the way to go. My friend wants one for his HZJ73 as well and I think the back L/H door is the same as my 78.
well there are lot of 2nd hand (genuine)+new available here in Pakistan.........my Prado came with the roof rack and ladder i think from japan as i m the first owner of her.it has a decal(Japanese written and LJ 78 showing) on the top of the ladder but it is vanished due to the weather conditions here
well currently i m out of town....but still i have some pictures hope they will help......as i get back to town will post detailed pics of the ladder and everything.
and you can see the curve in the middle of the ladder
