In the first picture you can see how the kit comes packaged.
You will also need depending on how you want to customize your driver:
X-Acto Knife, Fine tipped Deco color paint pens, paint brush and paints, contact cement, drill and drill bit.

The bodies, arms and legs are matched with each driver in line on the sheet/baggie.
Create replica's of the originals or mix and match to your creative desire :)

Scrape the excess plastic off with your fingernail or your blade.

Below is where you see the x-acto knife being spun inside the socket to clear out the plastic inside.
It should take care of all the excess plastic in the socket and make it ready for assembly. Test fit each piece as the arms and legs pins *may* need to be trimmed down a bit so you don't break them when
placing either the arms or legs on. They should go on firmly but with not to much effort. If it's not going on with a gentle push, trim down the back sides of the pegs ball ends and test again. You can also heat up the arm/leg hole by holding close to a light bulb for a few seconds to soften the plastic and then pop it over the peg and let cool again. Be very careful here as I've busted a few myself.

You will need to either cut off the peg on the bottom of the foot in order to glue on a small piece of a roll of magnetic tape (supplied) or drill a hole in it to fit the peg on the foot. Or just cut off the magnet peg and heel, as they stand just fine as the 2 in the back of last picture show.

Here they are,  ready for painting to your liking!
The possibilities are endless for colors on resin and painting.
(I'm just not a painter so mine stay like this) :)
