Standard for GTV are about 24mm.  GTV6 i think are about 28mm.  Vin is usually the best "local" place for upgrades.

28mm are the first 'upgrade' size.  Plastic bumper GTVs and GTV6s usually have 24mm (actually 23.something) bars, steel bumpered GTV and GTs normally 21? mm.

From the BB:- http://www.alfabb.com/bb/forums/milano-75-1987-1989/41095-drop-spindle-discussion-9.html

"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 -- ""

This is American specs presumably, I assume ours are the same but I'm not entirely sure.  "Milano" = 75
