Rear springs, shocks, How was it set from the factory! Options

[pek771]

Hi all,
I’m trying to find out how long the rear springs were from the factory. I think my old springs are shot; the shocks were. I have new Bilsteins. The old springs were like 12 1/2 inches long and I did not need a spring compressor to get them out. And the bottom spring perch was all the way up. It appears there are 15mm between the rings on the shock body.
So I just want something that’s gonna work, but I don’t know what the original was. What I’m really trying to figure out is if I have room on the shock absorber for any old spring.
I had a really lot of negative camber like almost three degrees. I don’t think the PO played around with it too much but somebody may have. Maybe the PO to the last PO. I’m thinking that the negative camber is from the springs being worn out and the shocks being worn out.
This is all much easier to do with no batteries in the way.

I haven’t even gotten around to looking at the front yet.
TIA
Pat
