Mounting Yakima Tracks on DCSB Leer Shell / Prinsu Ready

I am wanting to mount a Prinsu Top Rack on my Leer Shell on my 2012 DCSB. Prinsu recommends using Yakima or Thule "rack tracks" to mount the Prinsu feet to. Yakima offers track sizes as seen below. My DCSB needs a 42" track. However, this size comes with PlusNuts for installation on sheet metal. Of course my Leer is fiberglass - to which I would need the CapNuts. Is it just a matter of ordering the CapNuts separately? Will they work in the 42" track size?

Thanks Mates

Available in 42” (8001126) and 54” (8001127) lengths with PlusNuts for installation on sheet metal and in 54” (8001138) and 60” (8001135) lengths with CapNuts for fiberglass applications

 

Probably cheaper to just buy the 60" with the proper hardware, and then cut down the tracks to size. They are super straightforward to cut, and then you can have just the right length that will work for your cap.

 

^ Interesting. May be a good way to go. Thx

 

I'm in the exact same boat. I ended up ordering the 63" Rhino tracks because every other brand is out of stock. I just assume the extra length will help distribute the load or I can cut them down to size if necessary.

 

Just another fyi: I measured the tracks on my Leer, which were factory installed. They are 47" long.
