Does anyone know the structural and physical differences between the springs for R172 vs R171? Is there any way to make them fit in r171?

You need to see ht color marking your springs have. I will stick with r171 springs, not r172.
I change all the springs and shocks on mine.

Thanks. Its only because i stupidly bought the r172 springs from a private sale thinking they were compatible with 171. Guess I'll have to sell them somehow.
