Over the years, Triumph apparently used what ever was available to them at the time to assemble their cars. For one reason or another, much of these slight variations, even within model years, in un-documented. Well here's another one. GT6 models have air vents in the dash. Some also had a pair of these 'eyeball' vents under the dash right next to the center radio console/support. These were originally designed to put out 'fresh air' not heated air. It's the consensus, that the GT6 didn't need any extra heat as they are already infamous for being 'hot boxes'. Later model MKIII GT6's were built with many of the same components used to assemble Spitfire's of the same era. Why? Cost! Even though the latest model GT6 was a big hit in the U.K. the bulk of sales were in the U.S. Emission laws all but killed the sales in the U.S. Hence, the end of the GT6's production run in November of 1973. This GT6, built November 1972, has/had what is apparently, a Spitfire air box in it. What's the difference? The stock Spitfire heater box, has the 'footwell vents' on the sides of the box, and only two 'tube' outlets on the box for the defroster vents. The older GT6 heater boxes, had four tube vents on the box. Two in the same places as the Spitfire box, but two additional tube vents bottom center of the box. On the GT6 the two bottom center tubes fed the eyeball vents. These two bottom tube vents are 'inside' the heater cores, while the stock Spitfire tube vents, as well as the floor vents, are 'outside' the heater core as compared to the fresh air intake from in front of the windshield. |

This is the 'stock' air box as removed from Big Red. It's virtually identical to the all my other Spitfire heater boxes. In these photo's, the heater cores have been removed to simplify the visual differences in the vent outlets. The yellowish foam, glued to the boxes, is where the heater cores would have been. The cores would have been between the fan and the outlet tube vents signified by the green asterisks (*) |

In
this shot you can see the two extra tube vent outlets on the bottom of the heater box. (top
of the box in this photo as the boxes are upside down on the table in these photos) Then again, this all depends on how your under-dash vent pipes are hooked up. |
So, on Big Red, I've re-installed the older GT6 air box with the extra vents, rather than re-install the Spitfire type box I had pulled out. I'll need to acquire another set of eyeball vents to put under the dash to hook it all up the way the older GT6's would have had it. On one of the email lists I'm on .... a couple of comments returned to me concerning the various hook ups other GT6 owners have follows. The names have been removed for privacy sake. (They were willing to answer MY questions... doesn't mean they are willing to be bugged by you :-D ) ....my original email question/comment.... .... and a couple of returned comments........
