could be on those bottom tree bearings, so doesnt look like there's anything other than triple tree and steering stem frame housing that holds the bottom ones in except there is a rubber gasket that rides around the bearing flange on the bottom of the tree stem... in less something else went flying...
This is a great learning experience, picked up an angle grinder for cutting off all the unneccessary brackets, etc..., great tool, now I am thinking of picking up a low-end arc welder, will have to learn that but did years ago. Now how to make your own brackets, etc.... I know i can cut steel with a skillsaw and $40 blade, but for bending when needed not sure how to do that..... probably places out there where you can buy mounting brackets maybe and then weld them on yourself...?
