Seat slider designs?

[TXST8tj]

I am interested to see what people use for seat sliders.

I am building a 2-seater. I am 6'5", and my five year old son is.....not.
Due to my height and interest in riding in the cart with my son, I am considering two separate seats. The passenger seat will be fixed, at a distance that I can stretch my legs some. The driver's seat would be on a slider mechanism so it can be moved forward for my son.

There would definitely be some trade-off on my part where the seats wouldn't be too far back, but enough where I would fit and he can reach the pedals with the seat pulled forward.

Are people buying junkyard sliders from cars, or building something from scratch?
I had a thought about a piece of tube on either side of the seat, and then a slightly larger tube that goes over that the seat is attached to. There would be holes spaced along the chassis tube and a pin could be inserted to lock the seat in place.

I found these sliders. Not sure 5" is going to be too much help.

I suppose I should reverse my thinking to be that the driver's seat sits forward enough to fit my son, but it slides back to fit me.

With essentially 30" of height difference, he is not going to fit what fits me, but I can stuff myself to fit what works for him.

you might just consider a slider mechanism from a car. Or even two sets of pedals, one for him and one for you.

I know someone did this on the forum with pics, but for the life of me I cannot find it

You can do it like this.

^^^ hmmm, now that is interesting! Never thought about a dual pedal system....at least not like that.

Automotive-type seat sliders are good, but collect dust like crazy (because people oil them like mad) and then gum up.

I like that dual-pedal idea - K.I.S.S.!
