I am beginning to realize that I am an INCREDIBLY difficult person to deal with.
I caught wind that OPG has 3" lowering springs for the back (and front) of a G-body station wagon (along with other G-bodies). This is good news because I plan on installing "NASCAR" style spring jacking bolts/plates in the car to help balance the suspension/ride height in the rear - wagons seem to really suffer from corner lean.
So I call OPG to ask about their springs (

"Uh duh... we don't have the information..." - they respond
"Okay... who makes them for you?"
"JAMCO." - they say
"Excellent, thank you."
So I call JAMCO (
http://www.jamcosuspension.com) and wait to talk to a "tech adviser". Same round of "your question is too complex and I don't want to talk to you, please go away" BS.
Basically it came down to: "Oh they are custom ordered and would be made to that order by the factory which isn't here."
To which I replied: "Great. However, these springs currently exist because they are in OPG's catalog and can be ordered at any time. Now would you please call the factory, ask to talk to engineering and get me the spring rate for the rear 3" lowering springs for a 1980 Pontiac LeMans station wagon?"
End of day they said... I see the same thing developing that I got with Highway Stars and Factory Reproductions: radio silence.
