Why do´t you asked before. No Problem to explain it.
First : My opinion is, it´s not a clone of a Daytona Racing FSZ from a standard FSZ.
It is a modification by my "own spec." I do what i like and disclaim what i don´t like.
It is like ED said there are so many detail what make the difference respect to a HF ( or a Daytona)
Example, if you want install a 1,6 engine you have to use a first series one to have a Daytona spec.
I have a 1,6l second serie´s engine and i am not sure to install it in this Z undepent of original or not.
Maybe i will add. the 1,3 as it was in the car.
Also the gearbox. Dont have a fivespeed first serie but i can use a fourspeed first or fivespeed second serie´s
By the way, i build up an adapter to use the driveshaft second serie´s also with the fourspeed firstserie´s

`
And so on.
The cage : If you see the front bodystructure of this car you have to accept it or to improve the safety behavior
to stay a life after a front crash. ( don´t hope that it happend )
Second : I have a second serie´s FSZ in original condition´s
third : I like the shape
I try to keep as much as possible from the old substance. I was a long time in doubt with the flared wheel arches.
But i decide to do it.( I have had pain when i cut the old wheel arches, believe me .)
On the other hand a lot of Fulvia`s have flared wheel arches. Are they Fanalone´s or 1,3 HF or Daytonas.
Fore sure not. But the owner´s like it.
Look at the pic . from Koos. He has the front lamps like a Daytona but is it a Daytona?By the way it look´s good
but i will keep the serie´s one.
Comming to the end i have to summarize that i build it up for my own challenge.Not more and not less
