Front step pins for a 4MOD are not hard to make, just a little time consuming.
The best tire I have found to make them out of is the Losi buggy rear step pins.
Start by cuting a strip out of the center of the tire. You will see a rib down the center of the tire wher the two halfs of the mold come together. Take two rows of pins out of the inside half and one row of pins out of the outside half. The staggered rows make perfect cuting lines, make long cuts with your sissors so the edges are flat and even to be glued back together.
When gluing them back together, take your time. I use Losi treadlock glue and start with just a drop on one side. Hold the tire togethere and get the tread pattern lined up. Do a small section at a time, about 1/4" so you can keep the two halfs of the carcass lined up and even.
When they are done they will look like Losi Made them
