Philip -

I don't know about your "chirp", but if you had eccentric bushings fitted 
to your A-arms on only one side, your suspension geometry is going to be 
all messed up.  If I understand your post correctly, when you redid your 
front end, you found eccentric bushings on the driver's side, regular 
bushings on the passenger side, and you replaced them all with regular 
bushings.  (Do I have this right?)

Assuming that I do, your PO did some very strange things.  POssibly to get 
around a "tweaked" frame (though I hope it was just typical PO wierdness, 
rather than getting around a bent frame).  Anyway, the only normally 
adjustable thing on the Midget is toe-in, and doing just about anything on 
the front end will mean readjusting the toe-in.  (Particularly replacing 
eccentric A-arm bushings with the stock type concentric ones).  Eccentric 
bushings like what you found on the driver's side are used by racers and 
other folks who want to adjust the camber of the front end, though they are 
used on BOTH sides normally.

Short answer, get the toe-in adjusted so you don't scrub your front tires 
to death.  If the shop tries to sell you a "4 wheel" or "thrust" alignment, 
kindly repeat for them that you want the toe-in adjusted ONLY.  If they 
give you a hard time, go elsewhere.
