Here is a design of my push pull linkage for my steering wheel. I bought these parts from Home Depot the nylon spacer and 3/16 wood dowel. The micro servo are the sg90 and some other cheap micro servos.

1.Drill a hole on the side of the spacer slightly smaller of the size of a m2 screw. You want to make your threads while you are turning the screw. Once you are through to the inside of the spacer, back it out then slide the spacer onto the dowel.
2. Make sure the screws is long enough to penetrate into the dowel.
3. I cut a piece of the vinyl fence bracket to attach the servo with.
4.Once i figured out where to put the servo, I used plastic modelers glue to attach the servo holder in place.
5. I used my dremel to cut the dowel where it would line-up to the top of the servo.
6. Then I attach the servo horn to wood dowel. It fits
perfectly and it made its own groves into the wood. I used CA glue to glue the servo arm to the dowel. Next i drilled a small hole into the end of the dowel and screwed the tiny screw ( that came with one the plastic gear servo) into the end of the dowel to hold servo horn in it place.

This is my design for the arm movement. I used a hot glue gun to attach a piece of wood to the inside of the body. Then I used a double sided tape to hold the servo in its place. When everything is in its place, I use the hot glue gun to put the back on and glue around the servo.

Here is 3d part for for head lights for the Tonka. I bought a couple of small led flashlights from Ebay to use in the single headlight. The inside diameter is .700in.
The Double Headlight inside diameter is slightly bigger (.720in) because the flashlight was bought from Autozone.
I will design another single headlight box with the inside diameter the same as the double. Remember don't use CA glue it ruin the clear plastic....Continue Reading

The next step is to attach the front L bracket and the headlight/grill part to the front end of the body.
Find the center of the L bracket and the center of the body support. Hold it in place then use the drill bit to mark the holes of the body support to the L bracket. Next drill the holes slightly smaller than the screws you are going to use. The screws I used is M2.
The holes in the 3d body support is 1.95 mm.. if you want to a different size screws you might need to add some epoxy to fill in the space inside the 3d part.
This is the stl body support file just below.
