Hey Simins
My fc has a seperate booster mounted on the inner gaurd i thought that was original, if it isn't i'll find out what it's off and tell you, but it works fine in mine. (only a six though)
PS did you put the V8 in yourself?

Depends what look you are after. If you have room for the mastervac this is a much better solution than the remote booster. HK/T/G setup is OK if not a little on the large size, but has a metal m/c with metal lid.
Newer units are better such as Commodore with a plastic m/c body and lid. Late Commodore has a plastic booster as well as a fast fill m/c.
Another advantage of the Commodore m/c is that it has the proportioning valve built in.
All options are equally suitable for most brake upgrades as long as you choose one with 1 inch bore.
The Datsun booster is a little limited in vacuum capacity and may not pass engineers, this depends on the engineer you choose.

Russ thanks for interest yes i am installing the chev
myself using a CRS chassis kit and CRS hr front end
with HQ discs and calipers . will possibly upgrade to
aluminium HZ calipers the rear end is narrowed
nine inch with VN axels and discs and calipers
remachined to HQ stud pattern.
Ken thanks for your reply i have since looked at
a VT booster /master cylinder it appears the way to go
although i think the clutch master cylinder will
require a slight sideways relocation
thanks again for both replies i hope to be
at next melbourne meeting to join up
Simon

Simins,
I have the Hadfield front and and it is puss... Not much truning circle and scrubs inner and outer of the tyre. Not worth the money I paid. Mine is the front rack version, so the rear rack could be an improvement.
The half chassis on the other hand is very good.
If you were going with the Vt booster, why not stay with Vt calipers and rotors on the front. The Vn rears are also compatible for engineering purposes.
Cheers
jason.

Jason thanks for the input on the front end i bought
my chassis kit with the front end completely
rebuilt and powder coated having never been installed
so it was to good to pass up. Mine is a front steer rack
conversion. Am currently dont know if a rear steer rack
would give sump clearance for chev. I am running the
HQ stud pattern because of my wheel choice which are
7 inch pontiac firebird rims.A factory 7 inch version of
HQ GTS rims. Ill have to see just how steering lock is
when i hit the streets. Thanks again Simon

I believe you may have difficulty with your wheel choice.
A. HQ offset rims like the Firebird are dished much more than original FC rims.
B. HQ brakes on HR stub axles will also push the wheels out 24mm per side.
If you want to run a low stance the wheels will hit the mudguards. Try putting a 1 inch spacer between the wheel and the hub on an original FC front end to see where the wheels sit, especially during turning.

Ken i have test fitted the wheels they will run realy close
to the front guards . I have also purchased a set of
adaptors from Hoppers Stoppers to run a set of Leyland
P76 disc rotors,which have had the stud pattern changed to HQ pattern. Note this is for mock up purposes only. If it works succesfully a new set of blank drilled rotors to suit P76 with HQ stud pattern will be sourced through DBA. P76 rotors run approximatley 20 mm a side narrower track am yet to mock up and confirm exact measurement ,thanks for the input .This is a terrific site Simon
