Help! 924T Technical Spec Manual Lookup Please - Spring 477 411 105 M

[narmav]

I picked up a set of 924T springs which are supposed to be M471 springs. I don't doubt it as the fellow is I got them from is reliable. These were the M030 sport package for the 924T/931 series. I've read through all the notes on the M471 package and the M030 package, and I understood that the springs are both supposed to be ~160ftlb. I'd like to uprate my 924S with the 160lb springs were factory optional. My car currently has the ~130ftlb. My question/problem is that the part number on them is different than any data I can find.

The 924S/944 M030 springs are part number 477 411 105 G
The stock 924S/944 Springs are part number 477 411 105 Q

The one I have are part number 477 411 105 M

They measure to the same length (+-1/4"), and have the same thicken wire as my stock springs. The springs have four green dots/stripes on them. Anybody got a 924T/924 Technical Specifications Manual who could look these up?

That number checks out with the pair of M471 springs I have from my '80 turbo.
