I dont trust myself for shit when it comes to certain things LOL

 

small end facing the cab, big end facing the rear

 

What I was meant is, is the bottom of the block the square (looking from the side) end or angled end? That is, could the block be installed upside down?

 

Shouldnt be able to install the blocks upside down, the locating pin is on one end

 

Ohh I see what you mean. No, block was installed properly. However, what @jetas said I dont think the blocks would be able to be flipped due to the nipple on the top of the block, and nipple at the top of the leaf that gets inserted at the bottom of the block.

 

Oops. You're right. Forgot about that.
