What spec for rear springs?

YMGF · 5th August 2020, 15:46

Could anyone help me please ref deciding what rear springs I should have. Car is 75 saloon 2.5 Connoisseur SE of 2000 vintage. The car has a few "issues" which I'm uncovering, one of which is a broken rear spring. (And an interior resembling an Olympic swimming pool, but I'm close to resolving that one).

I've taken the rear squab out and there is no sign of the label that's supposed to be there. Also no sign of paint markings on the springs themselves, which are very rusty. Incidentally, the front springs are in much better condition and I couldn't see paint markings there either. Luckily the dampers are original at the front and had labels on showing the code.

Is there anywhere else on the car I could look to conclusively establish what springs should be fitted please or any helpful database you know of?

Many thanks,
Michel.

That's brilliant, thanks.

Actually, unless I'm missing something, (and as a newbie on these cars it's very possible!), it's not as clear cut as I thought. I can see I need "G" dampers but as for springs I need either the CI code, or the paint bands from the springs; neither of which I have. Is there another way to establish which of the 12 types of springs go with the vehicle I have?
Thanks.

Cut and paste from some years ago - would have thought of this site - so according to this a 2.5 v6 75 shold have red springs. As to the squab - i looked for my label twice with no luck - 3rd time a garage looked and they found it

When looking for the label under the rear seat cushion, I believe you have to lift the insulation as the label is underneath, apparently to the left side of the car.
