Fellow fiends:

Newell Burke asks a few questions about spring replacements.  I recently did 
that on Old Whitesides and can add a few remarks, fwiw.  

The rear end steering you mentioned is called "torque steer" and is now gone 
because you have new U bolts that are good and tight.  Torque steer occurs 
when the axle can pivot under acceleration, changine the direction of the 
rear tires.  This pivot occurs when the u-bolts are either loose or 
stretched (?).  Important: Don't forget to tighten them up again after some 
500 or so miles as things might seat a bit more and what was tight when you 
assembled the things isn't tight anymore.  (nb: my testy friend Brian sez 
that MGs can't have torque steer because they don't have torque.  I can't 
argue with him tooo much; he drives a TVR with a GT6 lump.  None the less, 
stop me from killing!)

As to fronts, I did them at the same time.  Put it this way: they are 
cheeper than the rear springs and much easier to change and wot-the-'ell, 
then you'll be sure.  The ride in my '63 improved noticeably with new 
springs at all four corners, though I have to say that it was the rears that 
were really gone (I mean it, too!).  The car doesn't roll (as badly!) and it 
sits "prouder" as well, though with some months now it seems to have settled 
maybe a fraction of an inch (it sort of looked like a top fuel dragster 
there for a while, tho it never did act like one).  

Cheers,
Will
