I got this set of lift blocks for my brothers MY. its a 4" kit.
I can't understand and install the gearbox blocks.
Why, in this case the alu block longer? and where does it go? front middle end?
Is 3 really the gearbox blocks? Its a set of 6 blocks, four of the steel and 2 of the longer alu blocks. (only 3 blocks of one side in pic)

In my L series kit and in a 2" kit i had on a brumby the 6 gearbox blocks were the same height. Thats why i'm confused with those blocks.
thx
