Anyone use these and did you have any problems threading them in? I'm in the process of replacing some of my adjusters with the .003 oversise ones and can't get them to thread in correctly. The stock ones are a loose fit on some rockers and figure the oversize adjusters would be a plug and play deal. No such luck. I have the right adjusters and the ones I'm replacing are indeed the OEM stockers. I first thought I had some bastard rockers but they check out ok. I've even taken the rocker arm off and apart to get a better bite and leverage on them. I can get them finger tight and start a thread or two before pulling crooked and start to crossthread. They just seem to be too big. Anyone know of a source for .002 adjusters??? These have me stumped. G.
