Need Def. vents/hoes

[oldblue1968chevy]

I need the def. vents (2) that go on the top of the dash and the (2) hoses that go from the heater box to the dash.

I was looking in the brothers catalog or something and they only have the vents in black (thats ok it matches anything). The old hoses were kinda plasticy, the ones brothers had were called/looked unlike the OEM ones..

Wheres the best place to get these vents and what hoses are better? Plastic or the 'other kind'

Hope this makes sense..

I know I can get these pieces from a junkyard, but they see alot of sun and generally deteriorate pretty fast..Or better yet, anyone have some there not gonna use?

Thanks guys!
