38mm radius arms... help

So I may have a problem. This is for a hodgepodge rover of various years.

Does anyone know the difference between the front axle bracket width for a 38mm radius arm vs. a 45mm radius arm?

My bracket is ~53mm I currently (i think) have the 38mm radius arms but I fear that they are too narrow and that is the source of many of my problems. I noticed this because I went to put in bushing NTC6781 and they look too wide for the radius arm.

Not sure if this is your problem or not, but the D90 radius arms are wider than the D110. I cut down the urethane ones that came with my kit to fit the 110, you may be able to do the same.

That does help, but my problem is that the brackets are too wide and the arms too narrow. I did not notice previously when I put the polys in. When I look at the new OE bushings they are too wide.

I have also had some steering suspension issues that I have never been able to fully resolve when I have gone through everything. I think this may be the root cause. As the poly's have worn thy have allowed the axle to shift, not good.

On a side note... we are shipping to Chile on Monday. last minute?

should be easy enough to find some thicker arms, Rangerover will do, or if you have metalastic bushes just press them through your original arms so they are even both sides

I thought about using the bigger bushings and getting it in the center but I need it to be 'right'.

My real question is... Are there two sizes of brackets as well as arms or are they both 54mm? ( I think so I just don't know so)

No worries, just trying to help.

I have wondered if the narrower bushes would give an easier suspension, although Landrover must have decided it wasnt worth continuing to make two different widths. I am using a disco front axle so have used the wider disco rods also.
