Springs for CGT

[Stephen Santoliquido]

I'm looking at springs for my '87.5 CGT.
FP says the stock springs for the CGT are the same as the 4K.
Eibach's site has applications for the 4k (Type 81) but not the CGT.
H&R's site only shows applications for the 4kQ.
Blau sells H&R for the CGT.
Tire rack has Eibach for 4k but not CGT.
shox.com could not quote Eibach nor H&R, but did quote B&G.
I'm soooo confused!
Does anyone know if the Eibach kit for 4k (1502.140) is correct for the CGT?
Whussup with H&R?
What about B&G or Jamex? Either of these would be cheaper that H&R or
Eibach. Do they suck or are they good (a more qualitative answer would be
welcome)?
TIA
