Actually... simply a drill bit and a thread bit will allow you to thread the hole in teh arms to M3...... Then use a file to file the splines off of teh original axles and a flat spot on them.. using a grub screw to hold them in place.... For the new axles a hacksaw to cut teh brass tubing, a file and the same thread bit will allow you to make the brass tubing to replace the suspension... quite simple.. and the picture below shows my how I gave it all extra support (note, I have not added the brass axles yet..I might do this as they break...)
