Does anyone know the difference in length between early and later front radius arm bushes?
Weirdly google seems very secretive on this point.

I have the part numbers NTC7307 up to 94 and chassis number KA, and NTC6781 94 onwards and chassis number LA onwards, now mine is chassis number LA onwards but is a 1993 car!

Any help much appreciated.

Thank you, that is exactly the info I am after.
Adverts for the bushes mention early narrow arms, so assuming narrow arms match to narrow bushes!

Thought they were the same length. It’s the bush size on the C ends that differ.
Changed sizes between 200 300.
Early narrow
Later large
Used to be able to tell the size change by a little triangle on top or the arm.

Are the top hat rubbers the same???
I just had a thought . Holes in chassis are same size it’s the thread size that may be smaller on earlier ones

I have no idea, one of the C bushes has been shedded for years now, and as I am replacing rear radius arms as they are rot, I thought I would treat the old girl and do the lot whilst over the pit.

Am getting old as cannot even remember doing that!
The other thing is I cannot remember is did I fit washers or replacement arms?

Thinking back (dangerous) :p I was looking for castor corrected bushes & the sizes were listed, a quick google might bring somit
up.
 
Another thing I was swapping axles as I bought two rebuilt axles with diff locks & radius arms iirc the front axle was wider
& didnt fit unless I fitted washers. They came off a 110 just to make things worse. 🤣 🤣
 
I will have fun when I swap the ones over on the son's Ninety, narrow arms and a Disco 1 axle which have wide arms. Must have spacers or the mounts have been adjusted to fit the arms.
 
I replaced a front axle on a mates truck for one from a Disco and just used spacers. Simple way is just to get the wider arms with the replacement axle if you can.

Could be a defender casing to allow the wide arms, same as my modded 109 with vented discs.
