Then you should be able to slide the extra leaf into the pack. It should be the third from the top. On some extra leaves the hole for the center pin is a little small and needs to be drilled out a bit larger. I had to do that with mine but it was quick and easy.
Once you get the extra leaf into the pack, use some c-clamps to compress the leaves back together and reinstall the center pin. be careful not to overtighten the center pin and it can strip easily. Then put the spring clamps back together and loosely install the ubolts just enough that the center pin will seat in the spring perch. Then you can position the axle to reattach the shackle. Once the shackle is attached you can tighten the ubolts and reinstall the shock.
So it's a bit more involved than just shackles but it's really not a difficult job. I think it took me just over an hour to do both sides on my truck.
This is great, thanks!! Definitely going this route once I have a bit more cash money. The only thing that worries me is drilling holes in the leaf - I have cave man tools.
Really want to pick up at least tires, sliders and recovery gear first so I can get out on the trail more
Btw do you think the wheelers type b steelies in 15x8 and 33x10.5 would be a good fit for my truck? A little worried about weight. Found a good deal on 96 4runner alloy wheels, think they'll clear the calipers? Waiting to hear back from owner about backspace. Will post a pic of them in a few.
Edit, found out these are same bs, 4.5. Would probably stance them out a bit with spidertrax down the road. Still looking for fit info on 1st gen taco
