Default Relocating leaf spings inward 67 mustang

Just wondering if anyone has ever attempted relocating the leaf springs inwards on a 60's Mustang? I need to get a little more clearance for 10.5 x 28 MT ET drags. The MT's fit, but they stick out too far for my taste. I only want to move them one inch inwards and have decided to chop away underneath. I have got one front spring pocket almost finished and am fairly pleased with the result. I have reinforced the outer sectioned frame rail with 3/16" plate and then added another 3/16 plate on the inside of the remaining frame rail side plate to make the width of the new frame rail slightly wider than the original. 3/16" plate is probably 3 or 4 times heavier than the original frame rail and the new section width will ensure that any torsion on this assembly will be handled better than the OEM design. I still need to weld in a 1" spacer outboard of the front spring eye but will wait until I have installed CalTracs to ensure pocket width is OK. Once I finish the other one, then I still need to weld new spring perches on the 9" and fab a set of 1" offset shackles. After that is done, then a little sugery on the front of the inner wheel houses and we should be good to go!

I have thought of doing this but there will not be room for tail pipes afterwards. Have you thought of moving the whole rear frame rail?
Do you have any pics with the MT 28/10.50/15's on the car and what rim size are you running? I run a MT ET street 27/10.50/15 on a 10" rim with 5.5" backspacing, with stock leaf spring location. Looks good!
