Runner bolt length

Ok, so I am dumb. I took my plenum and runners off to replace my injectors. I put all the bottom plenum bolts in a bag, but I did not mark where the longer bolts go and where the shorter ones go. Can anyone help? Thanks in advance for helping my stupidity!

Re: Runner bolt length

They are 3 different lengths. I did the same thing, didn't pay attention to where they came out.

The easy way to sort them is this: Lay both runners beside each other with the openings facing down. Now play a puzzle game by placing the bolts in the holes until an equal amount of thread is coming through the other side for all bolts. It's the thickness of the flanges that deterimes which bolt goes where.
