[TR] TR4A trailing arm shims

[Anthony Rhodes <spamiam@comcast.net>]

I have been upgrading my IRS axle to the Goodparts CV joint axles.  

As I did the second side I see that there are lots of shims under both the 
trailing arm brackets.  It seems to me that it may be possible to remove an 
equal number from each bracket.  I think that in this way it may be possible to 
preserve the geometry and get a bit more bolt thread available for the nuts 
holding the brackets.  

This will change the fore-aft and the in-out position of the trailing arm.  But 
do you think the trailing arms were adjusted to that they were perfectly 
co-axial, and equally spaced?   I would doubt it. I would havevm thought the 
shims were used only to adjust toe.

But then why so many shims?   I would have expected one of the two brackets to 
have zero or 1 shim, and the other bracket would be shimmed to get the toe 
adjusted properly???
