i used a crappy advanced auto one last time.. this time i want to make sure i put something decent in there.. Now summit doesnt sell the GM brand one that is probably best to use, but they sell one that is made for ford clutch style diffs like the eaton i have... here is the link..
http://www.summitracing.com/parts/CUR-99012/ ... just wondering of anybody has used this at all and if its the same as the GM stuff... im already ordering other stuff from summit so i figured id just throw this in there with it... they also have redline
http://www.summitracing.com/parts/RED-80301/?rtype=10 , and ford racing
http://www.summitracing.com/parts/RED-80301/?rtype=10 , are any of these better or worse for a 12 bolt with a eaton posi... just wondering... i could order the GM stuff at work tomorrow but prob wont see it for a couple days... thanks for any help
