Hi,
Does anyone know what size fittings I need to screw into the gearbox so I can make up some new external oil cooler lines?
I'm looking to run new copper lines to an external cooler.
Thanks
Jon

Hi Jon,
I believe the fittings are 1/8" NPT.
I would avoid using copper tubing as it can work harden from vibration and fail.

1/8npt is correct
Can't open your links at moment
Go on eBay
http://stores.ebay.co.uk/Torques-U-K
Cheap price good quality and amazing service
AN-6 seems to be the way
When using AN-8 it's been know to flow to fast and a reducer used to slow flow
Mount you cooler
Have a measure order the pipes
Watch youtube vid
Make your own it's easy
Tape pipe cut with angle grinder with thin Alu dish
Post up how it went as I'm next

Oh while your there
Oil temp sender inline mmmmmm
The 1/8 npt is an tapered thread so use ptf tape
All other an-6 fitting are flare and ball so no tape
I'm going under steering box with both lines then bulk head connector to front mounted oil cooler
I can email you a full excel spread sheet with all adaptors I'm about to order but might be diffrent as B body
I have done a lot of research into pipes and fitting and need loads and it's all mega money if you want talk after you added it all up and crying PM your number lol

Got Copper on mine, been there for years no probs...a cheap an easy solution.. Try and avoid using rubber hoses, seen them blow to many times and destroy the boxes...

How about braided hosr Rich ? 3M is about £25 and should resist popping ? (i've still got solids on mine, but was thinking of changing at some point)
