"No need; Potenziato from the alfabb was kind enough to copy a page from a shankle catalog as well as swap spindles with me (he has RSR coilovers and wanted to get rid of his drop spindles, b/c they put the coilovers out of their range of adjustment).
So after many hours under the car, and with a 9 foot long pole, I was able to twist my 27mm torsion bars enough to remove the A-arm bolts (I think 30 and 33mm torsion bars must requre the engine to be lifted enough to slide in the LCA bolts from the engine bay. Once you lower your 116 with stiffer torsion bars, the LCA bolts no longer clear the LCA! Before I barely was able to get it in by grinding part of each head of the bolts off to eek by the LCA.
Anyhow:
"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.
The dissapointing news is that on my Verde, the drop spindles with bump steer correction reduced my bump steer by a large amount, but at the limit, didn't seem to do that much for my understeer problem. It felt better driving fast on a relatively bumpy road (bump steer correction?) but on a freeway onramp, the front tire howl was still there. I haven't given up entirely yet though, b/c my front camber is at like -1 or less, about the same as I had before. This is kinda funny, b/c on Potenziato's 24V Milano, his camber was roughly the same after he went back to stock spindles as before! The drop spindles were 1 and 1/16th inches longer.
I haven't been able to go to my usual testing spot so I wouldn't call the results conclusive yet, but so far they did less than I was hoping.
I'm going to try to get my camber to around -2.5 or more this weekend but I'm going to my GF's prom so I'm not sure.
Hopefully the results will be better for you Echoleader!

The D-spindles looks like a larger drop than it is. It has a correction for bump steer too.
Also, Larry mounted the ball joint below the UCA! I didn't notice it until I looked at my own car.
