Wiper arm interference

[robbz28]

I have an issue that is giving me a headache. I installed a vintage air aftermarket AC in my 67, it works GREAT, looks GREAT, very very pleased with the kit, but my wiper arm rubs the ducts underneath my dash every time...I can tie them back, but I guess the bouncing of the highway settles them back in the way. Have any of you dealt with this issue? Was there some sort of shield from the factory? My car did have factory air, but it was dry rotted and full of rat excrement...anyway, any help is appreciated.

The factory setup had steel brackets holding the hose in place. Zip ties ought to do the job.
