Disco axle on early classic...radius arms

[TheKeymeister]

I've got an off roader hybrid truck based on a 1974 Range Rover Classic...

The front axle was totally knackered so we set about fitting a discovery one that was in stock & fully rebuilt and painted.

Unfortunately we then realised the radius arms are different, with the Disco ones being the later, thicker ones, and the original ones being the thinner type.  The original bushes were too small for the new arms, and the new bushes were too big for the chassis mounts.  The 'bodge' to get it rolling across the yard again was to file/grind down the newer bushes to get them to fit (ish) into the chassis mount, but I need a more permanent solution. 

Any thoughts on this? There must be a better way surely!  Can I use the early radius arms in the newer axle and space them out with something, if so what should I be using to space it.  This all happened many months ago now and caused it to get left in a corner, and I've had a sudden burst of enthusiasm again which is rare.

Just get set of later radius arms and bolt them up?

I've got the later ones, but (unless I'm missing something) the bushes on them are too big to fit in the chassis mounts, and the bushes from the early arms are too small for the threaded bit of the later arms to pass through

I don't think the chassis design around the radius arm mounts changed through the whole coiler land rover production run...

Any of the arms should fit the chassis end. It's only the axle end that is different.
