The Yakima SkyBox 12 Rooftop Cargo Box - 12 cu ft - Black Carbonite # Y07334 doesn't have a specific minimum clearance below the crossbars because each fit will be slightly different. My contact at Yakima estimates that the very minimum would be 2 inches between the bottom of the bar and the top of the roof, but to be safe you will want to consider 2-1/2 inches as the minimum so you can ensure the fit. view full answer...

The length of the rack can be adjusted to 80, 83, or 86 inches long. The rack is permanently mounted to the roof of your van. This roof rack has a 200 lb weight capacity.

Since there isn't any custom-fit trailer hitches for a 1978 VW Bus, what you'll need is a universal weld-on hitch. For that you just need to measure your frame width from outside to outside and if you need any specific drop for the receiver to clear the bumper.
If your frame width is between 18 inches and 44 inches, you can choose from the Curt Class V Universal Weld-on Receiver Hitch and Brackets with 10.865" Drop # 15902 or Curt Class V Universal Weld-on Receiver Hitch and Brackets... view full answer...
