Need help on 66 c10 Stepside Cross Sills
 

Looking for some intel.

1. How many cross sills needed? 3?
2. How many reinforcement sills? 3?
3. Rear cross sill. Does the top of the rear cross sill mount directly to the bottom side of the bed side bottom? Appears I have a small gap?

Thanks

There are three main cross sills and a rear support. Which on a step side makes up the back end of the bed. And two supports.

If you go to Mark-K they actually have instructions and drawings you can download or look at.
