Seems as good a place to ask as any... for someone considering doing a TC "replica" (won't be an especially accurate one, since the base vehicle is a Mk1 estate

), what actually makes a TC a TC, other than the obvious engine bits?
The car is a '74 and eventually I'd like it to be as close as possible to the TC trim level of the time- as if someone had walked into a dealership in 1974 and requested by special order a TC estate- obviously this will involve a certain amount of time part hunting. This is a fairly long term plan!
It's lost a lot of it's original trim and most of what is left is damaged so I'm not destroying a nice example of an SDL in the process, and I already have a Marina TC engine to go in- the car died long ago, donating it's engine & gearbox to a kit car project that never happened.
If people have comparison photos for some of the more subtle bits like the doorcards then even better
If any of the bits are common to other vehicles I guess that would be handy to know too.
I'm sure this is already covered on here somewhere but I couldn't find anything despite trying various search permuations.
