defrost kit Kit includes all parts needed for installation.
defrost sideM The angled connection will keep hoses clear of wiring, hoses and radio equipment.
defrost edgeM The top surface is gently curved to conform to the underside of the glareshield. Heavy-duty construction=long service life.

You may discover upon removing the glareshield that your old hoses are unusable. Original equipment hoses were made of the old CAT material (black, string wrapped, and probably now hard as a rock) Even newer SCAT hoses (orange, siliconized cloth) can have frayed ends or be too short to properly attach to the defroster vents. We can supply brand new SCAT hoses(sold separately) pre-cut to the correct length for your installation with ends pre-dressed. Simply remove the old hoses from their retaining clamps and put in the new for optimal performance of your new defrosters.
