My revised cross sill locations are as follows:
2nd - 26 3/8" (same as Mar-K) - also a frame mounting location
3rd - 44 1/4" ( moved back from Mar-K 35 3/16") - floating cross sill
4th - 63" (this is the same location as the 5th from Mar-K) - also frame mounting location
5th - 74 1/4" - this is basically half way beween the 4th and the rear cross sill - floating cross sill

This places one floating cross sill approximately midway between the 2nd and 4th frame mounting locations and one floating cross sill approximately midway between the 4th and rear cross sills.
