l67ss Posted March 12, 2015 Report Share Posted March 12, 2015 5.5mm Quote Link to comment Share on other sites More sharing options...
Nas Escobar Posted March 12, 2015 Report Share Posted March 12, 2015 5.5mm, is that the socket size? No way it's the bolt size, they look at least an inch and a half long. BTW, to the O.P., you can get the botls from the junkyard from any GM car that has a v6. They're universal. Get em of a 3800, 3400, 3100, whichever. They're the same bolt.
