here is a pic of the modified mulch kit
and a pic of my cardboard templates taped into place
the left side mulch kit baffle only needs to get the baffle between sections removed but the right side mulch kit baffle needs to have the baffle between sections and the end plate cut off then adjust the angle so it exits right and have a tab welded to use an existing hole in the mower deck to bolt it down. There is even already a notch on the underside of the mulch kit that let me slide the tab under the baffle and weld it to the outside of the baffle so it wouldn't disrupt the flow of air under the deck. I used a piece of 3/16" angle iron for the tab.
