TR6 frame repair:trailing arm sections.

[John Jacobsen-Watts <Johnjw@interlinq.wa.com>]

Has anyone replaced trailing arm sections in the TR 6 frame?  My question 
concerns alignment.  How critical is this? Can I count on shims to correct 
marginal frame errors?  Has anyone used an alignment shop with a jig?  Was 
this expensive?  Any special concerns?

Any particular recommendations for bushes for the trailing arms?  What about 
the springs?  I am using a set color-coded red and green (old ones were 
green and white). Do these colors mean anything to anyone?

Also:  Does anyone have a hardtop for a TR 6 they wish to sell?
