By the way, leveraging the question, I've received my brand new monoleafs from Calvert but currently I'm running with Assassin Traction Bars that require drill a 5/16 hole at leafspring to attach the front link of the bar.

Question: Some problem to drill this hole in the front segment of leaf spring?

Thanks
