VBP mystery spring rate
I am thinking about buying a rear fiberglass NOS VBP spring.
I would like to know what spring rate it is.
It has a sticker with the box "PRM" checked off.
I assume that means performance.
However, there is no rating listed, and all the other ratings on the sticker are not checked off.
Does anyone know what spring rate this spring has?
Thank you,
Harry

Here's a photo of my VBP spring label and I don't see a "PRM". Can you post a photo of the label you have?

I purchased my VB&P spring in the mid 90's. The sticker on mine is just as post number 2. With a hole punched out under the spring rating.
also, as stated above. No mention of the rating you described. Mine is absolutely identical to post number 2.

It was DRM... it was a dual rear mount spring. I don't think the guy had the rest of the setup, as I asked.

On my spring the spring rate was stamped into the metal end cap near the bushing cup, bottom side. See if he can get photos of those areas.

I'll add that
@augiedoggy 's thread has pictures. If you know what the spring looks like, posting a picture is much more helpful than describing it.

DRM is Duel Rear Mount. Its intended for there C4 style rear spring set up that had the Aluminum Bracket that held it. If it was DFM it would be for the matching Duel Front Mount Kit they sold. This is a spring that I would be interested in buying as I have the rest of the set up.
