The rubber is pretty shot, and unfortunately, they are heavily glued to stock wheels, which have also seen better days. So my first order of business here is to try and replace the axles with something that will accept a wider array of wheels. Hex adapters seem the way to go, but dropping the ones from my Kyosho Lazer ZX on the stock Invader axles leaves a couple cm of space between the back of the hex adapter and the carrier hubs/bearings. I don't necessarily mind spanning this space with nylon washers, but would like to have a tighter fit if possible.

From left to right are Tamiya, Kyosho Lazer, and the Invader axles. Tamiya are the right length, but the cup rubs on the inside of the carrier (a real bummer, as I'd love to mount some gold rims on this!). The Kyosho cups fit just fine and spin freely, however the taper is too far out on the axle and creates an even greater gap between the hex and carrier hubs. The cups are also a bit longer, which is perhaps too snug a fit with the stock dog bones.

Any Invader owners out there who've found a good fitting axle to replace the stock? Lots of info on the Zerda, but I've only found a couple posts about Invader mods, and the one that mentions hex adapters does not give specific info.
Thanks in advance!
