...however that is the conclusion I came to - everything lines up too well in either position!
Mine may be unique now, then, with it's carefully machined aluminium spacer...
I had the oddly spaced plastic bodied heater fitted to my new December 69 Cooper and the thing wouldn't get the car warm at all regardless of where the fan, knob or blower was - if you'll excuse the phrase! I resorted to parking up and letting my then girlfriend warm me up......, but I digress......
When I drained it down and stripped the heater out I found the same 'problem' with the wide brackets and narrow heater. I worked it out that you just positioned the heater in the left/right position where screws that held it up to the dash rail aligned with the threaded screw clips. I don't even remember mine having nuts on the left and right extended mounting bolts (1/4 UNF?) although I did put 4 on (2 inside and 2 outside the brackets to lock the heater up.)
I also found that the heater matrix entry and exit pipes were on the right/drivers side of the heater. This meant that the heater hoses came into the car on the left side as per normal, then did a sharp 90 degree under the dash and above the heater then another couple of sharp right and left handers, kinking as they did so until they reached the matrix outlet and inlet. No wonder that the thing didn't get any heat............
I stripped the casing down, breaking the spring clip thinggies as I did*. I just bored identical but symmetrical holes in the opposite side case of the heater, turned the matrix round so that the entry and exit pipes came in and out of the LEFT side of the casing. Cut about 50 yards off the hoses, put it back together, connected it up and it worked pefectly after that.
*I wrote to Smiths Industries who were based at Witney locally and they sent me a big bagfull of the one-way trip clips. The technical man there said that these heaters were a cheapening exercise to standardise them for the range of all/most BL cars....... Enough said!
