Rons Machining service has them for 385 i think. WELL WORTH IT! my G80 almost put me in the ditch when 1 tire stopped spinnig and jerked me to the ditch. the bad thing is i know i have to change it PLUS i have a tru-trac yet i havent changed it out yet. the G80 wouldnt even stay locked when i was launching at 2500rpm behind a stock 5.3 it has caused me to run a lot of 15.0s @ 94.5-95.2mph bc it wont keep the tires planted during the 60'
