Just found a picture of my mini prior to taking it apart.
turns out the reducer is not at the firewall but rather at the stiffener plate on the fender.
so that is where I will put it.

thanks to all for your feedback.

 I know you guys are talking about reducers, but I have a front metal screen that goes on the front part of the heater hose. Is that proper?? Or did it come off of something else??

The build date on my “S” is July 7.
So.... I will place the reducer next to the firewall.

The earlier '66 style you reference (and also part of 1965) extended the large diameter tube from the firewall to a bracket screwed to the stiffener panel. That was a senseless design because it sucked hot engine fumes into the car as "fresh air." Prior to that configuration, it was a full size tube from firewall to the grill. 

Hope that all makes sense!

I recently had to chase down all the parts from the firewall tube forward, for my restoration. Catmint UK sell a complete MkI/II "reducer" setup with everything except the plastic intake grill piece. That was incredibly hard to find, eventually found a decent used one in the UK.

Interesting, and good to know. June is a few months earlier than I thought on the change. The reducers are some of the last changes to the models (along with a double skin bootlid) that carried on into the Mk II models, if I recall correctly.

Thanks
makes perfect sense.

the owner of the car I saw indicated his set-up was original.
since I had never seen this I wanted to verify.

Recently saw a 1966 S with the fresh air hose plastic reducer (large hose from heater to small hose to grill) positioned at the stiffener panel on the side wall.  

This is is the same place where the fresh air hose for an early 1966 S terminates and held in place by a bracket screwed to this stiffener panel.

Is this the proper location for this plastic reducer or should it be closer to the firewall.
