Brake Servo For Hawk Hf 3000

[CHARVIN]

Hello,
Can somebody tell me wich brake servo (booster) is the best for the HF3000.
Has the FIAT 131 a 178 mm or a 152 mm diaphragm?
Is a FIAT X 1/9 suitable ?
Where can I find them.
Thanks for your help

131 is 158.5mm
132 is 160mm
X19 size isn't given in my Haynes manual.
I've removed my servo when I changed to dual m/c balanca bar, but I've still to find out if I'll want to change back!

Thanks for your reply?
May I have another point of view or experience from somebody eslse

Will the Fiat Argenta (1982 on) with a 178mm diaphram fit?

The X1/9 has no booster...you are out of luck there.

But is a FIAT 131 booster with a diameter of 178 mm OK ?
If not where can I find a FIAT 131 - 158.5mm or a 132 - 160mm
