Default help, need ideas for leaf spring suspension

I bought a Tamiya TLT and im trying to make it into a scale truck.

I was going to do a 4 link, but didn't have the right links and it ended up having bad torque twist.

Now I bought a set of Tamiya F-350 main leafs.

I thought I could whip up some shackles easy, but had trouble. the length of them seems to be really important, to short and the leaf binds and to long and you over bend the leafs.

I had seen the video below a while ago, and thought it would be a nice option. BUT, I cant think of the best material or item to use.
I find I can often take one thing and make something else out of it (mod it) but fabbing from scratch I have trouble. I don't have the best skills and lack some tools (ie, cant machine anything)

so, if you guys could watch the vid and help me think of anything that would be turned into the sliders:

Just a quick thought. maybe parts from inside a dvd player. there is a bar and a slider for the lens that moves in a similar action as as the slider in the vid. i used to mess with dvd based game systems before i got into hobby rc and that was the first thing that came to me.or maybe some small drawer slider parts. or some rc bearings, small L channel with stops at the ends.
the toothpick is in place of the slider bar that i don't have any more. like i said just some quick thoughts.

no, I couldn't find anything that would be smooth and the right dimensions.

I did however come up with something that was not a typical shackle setup.

I used a steering rod...one end to the chassis and the other end threw the eye of the leaf. the rod can flex both rearward and upward, giving the leaf the movement needed. It doesn't flex as much as the front leafs which have a more typical shackle (made from servo mounts) but it does work.



I think it would be cool if a RC company would make the slider type shackle for a scale RC. Seems like a nice simple thing that would work well.

Looks good and serves the purpose. have you tested it on the trail?
I agree that the sliders would be a good option to have. after i pick up a trail truck i might try something similar.
