Just bought an 86.5 NA, this isn't my first rodeo but I have not seen this before. The wrap around pipe that feeds the heater core is capped off on the drivers side with a welded cap and the hose runs to the firewall from the passenger side. Usually it is just the opposite and the cap is a rubber cap with a clamp holding it on....is this normal for the 86.5? I have had several mkiii's from 87-91, both turbo and na, but I have not seen this on any except this one....
