WOW. Not sure that is even possible. Not sure if the pin taper is the same on both, as well the length and diameter!

Then there is the fact that the top b/j has 3 bolts the same size of each other, and, the lower has 4 bolts - 2 different

size of the other 2. Has the lower control arm been modified?, cut?, and rewelded? But, to answer your original

question, from the bottom.
