H&r Spring Numbers?

[Carl1974]

Good afternoon, It’s time to sell on my H&R springs either as a full suspension or possibly seperate, however how can I tell if they are 40 or 50 mm drop.
The springs have part numbers but I can’t find any corresponding information.

The H&R springs with a part number starting with a 9 is a Euro Car parts special , only available in UK I understand . its a 50 mm kit
H&R don't list this in their catalogue at all , their normal kits are 29270-1 - 2 -3 -4 ( 4 types for different applications )

Many thanks for your info Crs performance, at least I can now advertise them with the correct mm depth.
