I would be interested to know if anyone has the factory spring and shock rates.. including length and diameter?
My thoughts also on this is that this was 30years ago and how much testing with springs and shocks was carried out back then!! not alot i feel.

That description sounds like the shocks that were on the front of my rally car when I got it (we weigh the same and I had a really hard time getting them to compress with my body weight, I think I used the weight of the car to compress them so I could get them back on!). If mine were based off of the specs that Jordan posted they might have been 430lb rebound/176lb compression ("rally valve + 10%").
The standard Bilsteins usually have an 11mm shaft. 14mm tends to be their large shaft. Is that what was on the shocks you have/had? If you have them you might be able to find someone with a universal testing machine who could put them into it and compress/rebound the shock and take measurements of their rates. I think the rates are given when the shock is compressed/rebounded at a rate of 1 inch per minute.
I used to have a spreadsheet that had calculated spring rates on it including the S&R front springs. But I can't find it right now...
