It was an oilite bronze bushing. Make sure it fits your input shaft and it should press fit, (use an installer tool or an old input shaft and gently tap it in) in the end of the crankshaft. If there is an old one present, pack it full of hard grease and use the same tool to hydraulic it out.
Sweet thank you. Good info to have in the next month
