Bill,

Is it so that the '71 T2 heatexchangers originally
came with the same operating-levers as a Bug, the ones
that pivot on a welded-on shaft, on the sides of the
heatexchangers that are closest to the center
of the car?

If so, i understand that you think the heatexchangers
you have know look strange, i think you have post
'71-'72 ones for the 1600 bus engine, which was still
used outside of the US after that date.
The heater-cable-tubes were relocated to serve both
the 1600 and the T4 engines. The levers of the 1600
heatexchangers had to be changed accordingly, and were
replaced by a small lever on the opposite side of where
they were located before. The levers are approx. 2" x 10mm
and have a small hole to connect the heatercable hardware.

Some Danish manufacturers produce heaterboxes that have
both this late T2 lever and the "Bug" lever and shaft.

Is this the answer???

Cheers,

Brian.
