Thanks Absinth.
Manual carbs and i have auto's ...BUGGER!!!
Ah well not changing them.

[Absinth]

Agro, the numbering for manual or auto carb isn't always accurate so I wouldn't worry about that too much.

[agr071]

To easy.
Thanks :D

[Absinth]

Actually..... :o I give you a bum steer.... they are all apparantly off Auto cars.... even number are auto not manual... last digit..IE.. 17057294 number 4 is even number= Auto

i can scan in the rochester date / application system if you guys don't have it

also somewhere i have the ww stromberg numbers which i got off the net

if your at a swap meet or in a blokes shed and you don't want to piss him off by looking up numbers a quick reference is:

704xxxx small primarys big secondaries 1965-70
704xxxx 'normal primarys and secondaries 1971-1976
1705xxx 1976-1979
1708xxx 1979 up

basically if you find any of the early ones 1965-70, the matching number dudes will probably give you good money for them on ebay etc.

[adam perth]

this may clear it up,
its probably better to talk 1708xxx carb than "604"

i find the 602,603,604 australian system confusing, as its not stamped on all
what do we all think??
