that looks about right. didnt do the math, but from other plans i have done in the past its relatively close if not exact.

ive looked at those but my box needs to be 15.5 MAX at the height, i would like to use the one that is 35.25x18x16 but the 16 is to high how can i change that box, if i wanted 15.5 H can i extend the length (i can go up to 40)
