Hey what's up, yes a friend of mine just installed them on his screw, and he had to bend the seam of the bed right above the shackle to allow the room for it under their... But I have done that on my old truck so I know what he means, also he used a mcgaughys 3" shackle I believe, and I used a 3" drop shackle from eBay... The brand is top gun customs...
See the seam bent above the shackle ... That's what needs to be bent and folded over. Lol this was not my doing, mine will no look like that I will cut two slits and fold it over completely lol
Hope this helps
Thanks
Ryan
