From post #122:

116 & 119 Alfetta/GTV 6/Milano Torsion bar specifications:

GTV6 Early model:
stock bar:
Rate -- 96lbs/in Diameter -- 23.5mm Length--989mm
Sport Bar:
Rate -- 134lb/in Diameter -- 25.4mm Length -- 989mm
SS Bar:
Rate -- 179lb/in Diameter -- 27.3mm " " -- 989mm

GTV6 Late and Milano:
Stock bar:
Rate -- 93lbs/in Diameter -- 22.8mm Length -- 932mm
*No wonder I hit my oil sump so often with the stock setup!
Sport:
Rate -- 143lbs/in Diameter -- 25.4mm Length -- ""
SS:
Rate -- 191lbs/in Diameter -- 27.3mm Length -- ""

So, I have an '84 and I think that means I have the longer, early style bars.

Another interesting thing I learned was that the GTV6 has stiffer rear springs in the rear than the Milanos do. I'm not sure how much, but the SS springs I have in the rear (143lb/inch) are 39% stiffer than stock on the GTV6 but are 57% stiffer than stock on a Milano. Also, SS springs apparently came in two lenghts, one that lowers an early Milano by 1 inch, and another that lowers it 2 inches.
