Before mounting it up, I measured the side-to-side spacing of the stock leaf springs is 74mm. The TLT's spacing is 79mm. So I'd need to space the leaf spring hangers and shackles out 2.5mm per side. I just used some 2mm spacers because that's what I had.
Front (hanger): I'd like some longer screws here. Not too confident in the lack of thread engagement, but I lack the proper screws at the moment.
Rear (shackle):
And installed! I'm just using 6mm long screws (4 total), but the axle really feels secure. That could be sufficient, but I will likely drill all the way through it for a little more peace of mind.
