Truetrac/Torque Worm LSD differential questions please

Good day guys.... actually could be better, broke parts in my rear diff today (axles look ok and theres lots metal in the diff oil!).
Questions: Looking at ordering a Truetrac and there website shows 2010 camaro SS part number 912A686 and gear ratio of 3.45,3.73. Does that mean i cant use our stock 3.27 gears???

Anyone have experience with the Speedmaster Torque worm?? Very little info online. My 2010ss is street car with some road track use, 470rwhp and 610rwhp on nos.
NOTE: i do not have wheel hop: full poly everywhere, all built rear susp.
Thanks, Jay

Note: I got too worried about taking a RISK on the unknown speed master torque worm and ordered a Eaton truetrac instead. Thanks guys

I can confirm the TruTrac works with all available ratios for the 218mm Camaro SS rear end - I have validated directly with Eaton.
