Thanks everyone - think I understand now.
My TCS never had the blanking plates in question (they had already been removed)
Note: I bought my car in pieces - when I was young and didn't know much
No worries!
I shudder to think of the things I did on 444R (photo below, taken in Antioch Park, Overland Park Kansas, September 1983...younger, skinnier, and no grey hair) a few months after I recommissioned her back in the early 80s...but she has survived up to now (and the new owner in North Carolina has pretty much stripped 444R down to the pivot bolt on the shift lever to start the third life)...I am a bit loathe to admit that it was me who did it. But then, in 1981, we didn't have the breadth of knowledge, certainly not the community of people to bounce ideas/questions/debating points/etc off of, not to mention the almost instant access to manuals, tech info, photos, parts catalogues...we were pretty much on our own (and spending time on the phone with RD, Dave Bean, Fantasy Imports, Frank at Sports Car World, and others...devouring the shop manuals, memorizing the parts diagrams, hoping the next issue of ReMarque had a Europa tech article, and trying what made sense at the time). That my effort in '81-'83 lasted this long and the car is still among the 'known examples'...well...blame luck more than anything else.
I always say, when I learn something new or have to change a preconceived notion, "that's great to know!" and put it to use on the next go-around.
