doubt if you find many plans for a leading link
some use steel on steel for the pivot... bushings are better ... as are bearings...
some build a springer with the shocks at the bottom.. with nothing tying them together behind the wheel,,,,,.. that is a springer with shocks at the bottom lol not really a leading link
EuroTrike is making an Earles type(leading Link) front end now for ElectraGlides and Goldwings. It will also take an automotive tire. I saw one being installed yesterday at Crossroads Trike in Salt Lake City. I was in pricing a new trike.
As to finding planns to build your own,awhile back just for the fun of it I googled leading like front ends and did find a web site with construction plans.

I would replace the shocks with a solid strut to start with. see if it bounces then. If so then you may have a problem with flex or the tire itself.
If not then you have a shock problem. My first guess is the shocks are a bit stiff or dampening is too light. It looks like you did rake the bike (cut the frame) Which is true rake and will add a lot of counter steer or caster to your ride. A steeper rake angle and offset trees (trail kit) will lighten steering quite a bit.
I have run many bikes with true rake and it can be a tough deal - Ask Peter Fonda what he thinks.
