<VV> LM clutch return spring question

[John McMahon]

I have a 1965 Monza coupe, and while I had the engine out, I performed the 
operation described in the Tech Guide on p. 6 of the Transmission section 
(Noise Reduction in Stick Shift, by Milton Binon).  Seems like it should 
work, but now I have nowhere to attach the short spring (the one that 
attaches to the bracket bolted to the body).  But what exactly is the 
function of this spring?  It is not the return spring (that's the long one 
attached to the differential), so what does it do?  Is it essential?  I know 
that GM would not have spent the dime it cost them if they hadn't felt they 
needed to.  I'd just like to know why they did!

Thanks,
