VPI HW-19 Springs

Maybe someone can refresh me as to which springs went with the VPI HW-19 series, Mk1/3/3/4, I have a HW-19 that started out as a first generation HW-19 and updated over the years to Mk4. I have multiple sets of springs that are black, silver and gold. Some of the spring caps are stainless steel, others are black plastic and others are black plastic with three silver metal dots on top. If someone could narrow down the correct springs for the MkIII and MkIV I'd appreciate the help.

The difference in color of the springs was for the amount of
tension/compression of each spring. I do not recall which
color went where on the table.

IIRC, the springs with the all black plastic top were from
the MKI, the black top with the three silver balls were from
the MKIII and the stainless steel tops were from the MKIV.

When I went for the Mk IV upgrade, my springs were all black caps with the three silver dots on top, but two were silver and two were gold. They were to go as follows... the two silvers in the opposite corners IE: one silver in the top right corner & one silver in the bottom left corner. The silvers were tuned to different frequencies than the gold.
