1950 3100 rear shock mount with Explorer rear end

[Dongray]

Im interested in switching to the 8.8 rear end with a 59.5 inch width but dont see how it can work with the stock shock mounts due to already limited space between the lower mount and the tire/wheel (see pic). I would assume using the narrower axle makes the clearance worse and in order to use the 8.8 rear end I would need to move the mounts to the inside of the frame or perhaps change to something like the TCI parabolic kit but besides changing out the rear end and tranny I was trying to stay original. Any thoughts?
Thanks
