I blocked mine off and don't miss it (never really had it since getting the truck). Not worth the money, work and aggravation to fix it IMHO. Even if using the flexible hoses, which apparently aren't that flexible, it would cost at least $400. I used this:

Just one thing I neglected to do when I converted mine to a single system is I didn't replace the orifice tube. The original one (gold I believe) is for the dual system whilst I should have swapped it out for a white one. It still works, just takes some time to cool down.
