XXX-81A. This is the BEST quality replacement heater channel assembly available and comes completely assembled & welded with the running board fastening panel - the bottom plate (with the threaded holes for the floor pan bolts) -the inner rocker panel area (where the carpet attaches) and the complete inner heater tube which brings the heat from the engine to the dash. Made in Denmark by JP Group-Dansk - these are the finest channels available. Please note, there is a second manufacture of these channels also in Denmark, this company is Klokkerholm. They made a good quality heater channel, but it is not as well made as the Dansk channels, and the Dansk channels weight almost 20% more because they are made of a heavier gauge of steel. If you want the best, BUY THIS DANSK MADE HEATER channel. And when comparing this heater channel with our competitors, make sure you find out which heater channel they are sell you. FITS: STANDARD BEETLE 1969 to 1977- left side only. We also offer the Klokkerholm channels sold in matching pairs, See VWC-113-898-045-L.
