I've been doing research... I am planning on a 2" body lift. In the interest of helping others I did the math. If anyone finds an error please feel free to let me know. I couldn't find anyplace that said how long the factory numbers are, but could find how long the 3" lift kit bolts are. Based on that, I did the math to find the lengths for the 2" and stock heights. The Numbers for the MM are accurate, the Inches are rounded. For the mounts under the rear of the front seats, I took the given length of the 3" lift rear cargo area bolts, then subtracted 3". This gave me the stock length of the rear of the front seat bolts. Then used that info for the stock and 2" lift bolts. Again, if I did anything wrong, let me know.
Body Mount Bolts Stock
Front mounts - 105MM = 4”
Mounts that are in front of the front seats - 65MM = 2.5”
Mounts just under the rear of the front seats - 50MM = 2”
Mounts in the front of cargo area - 85MM = 3.5”
Mounts in rear of cargo area - 125MM = 5”
Body Mount Bolts 2” lift
Front mounts - 155MM = 6”
Mounts that are in front of the front seats - 115MM = 4.5”
Mounts just under the rear of the front seats – 100MM = 4”.
Mounts in the front of cargo area - 135MM = 5.25”
Mounts in rear of cargo area - 175MM = 6.75”
Body Mount bolts 3” lift
Front mounts - 180MM = 7”
Mounts that are in front of the front seats - 140MM = 5.5”
Mounts just under the rear of the front seats – 125mm 5" (or stock bolts from the very rear mounts)
Mounts in the front of cargo area - 160MM = 6.25”
Mounts in rear of cargo area - 200MM = 8”
Edited 4/2/2020 for accuracy. If you'd like to figure your own lengths, 1" = 25.4mm
