Looks like a spool axle for 1/12th scale to me...

this bolt pattern fits directly to the spur gear. The hub where the wheel mounts to is on the other side(right side hub). I think the right side hub needs to be of the clamp on style to accommodate this setup. These are currently out of stock.

Place a ball bearing in the gear's center hole, I use an unflanged bearing here, but again personal preference. Lube the diff ring with your diff lube, lots of choices here, I use a high pressure grease that I can't find anymore, not sure what I'll change to when I run out. Slide the gear on the axle. Be careful not to get grease on the threaded part of the axle. Install a flanged bearing in your diff hub. Now install the remaining diff ring on your hub, a dab of grease on the back side will help stick it to the hub and make it easier to assemble. Again be sure the ring sits flush against the face of the hub. Lube this ring. Slide the hub on the axle. Install a flanged bearing in the outer hub opening. Now, if you press the hub lightly into the gear while holding the axle, it should turn smoothly with just a slight resistance from the diff lube. The next step can vary. Most people use the diff cone, the tapered spacer, next. Place it on the axle with the small end against the hub bearing. Place one or two bellevue, or cupped, washers in the large end of the diff cone, cupped side in. Thread the nut onto the axle and tighten until all the play is removed. Rotate again to be sure it is still smooth. If not try replacing the bearing in the outside of the hub. Put the axle in the car. Place the left hub, usually a clamping hub to keep from damaging the axle, on the end of the axle. Install tires on both sides. Measure from the chassis centerline to the outside of the right or diffside tire. Now measure the same distance on the left side. They should be equal. If not add spacers to the shorter side to make them equal. Now measure from the outside of one tire to the outside of the other. This is normally 235mm. Add spacers equally to both sides until it is. Narrowing the rear track from 235mm is a fine tuning tool for handling, but most people go as wide as possible. Now hold a tire in each hand and try to turn the gear. Gradually tighten the diff nut until you can no longer turn the gear with your thumb. You're ready to test it on the track. Slightly tightening or loosening the diff is also a tuning tool, but these adjustments should be small. If you skip down to page 18 of this PDF there are pictures of this assembly starting with step 55.

Thanks Lonnyj1950 , these are excellent instructions for a standard slipper diff but that is not what I was looking for.

You mean this one??---> https://muddslidemotorsports.com/23spax2.html
That is indeed a spool axle
Didn't know they used them at all in Pro10 cars
This is probably the other parts---> https://www.muddslidemotorsports.com/1spsp2.html

Default new carpet track in NorCal

So after a 12 year absence, i'm thinking of dusting off my CRC Genx 10LE. It appears the 235mm conversion kit is disco'd on CRC's website. Is there anybody else that makes a conversion kit for this car?

Thanks,
Steve

Use this - https://www.tqrcracing.com/rc_tools/rollout.asp

Also can get one for the phone-- I use RC GearCalc -- it's on Google Play. Quite handy on raceday

I called CRC last night. Their new #1813 235mm chassis currently comes with their widening kit (uses the 200MM rear axle), but apparently they are working on developing a true 235mm rear axle for it.

I have been running the CRC car on asphalt this summer with the adapters, it has been very competitive! Running against Xray, Fenix, and Roche, and have finished on the podium almost every race. A true 235 axle would be nice, but certainly not nessasary!
