I'm not sure. Came with: full white nylon black b-stamp, bearings stealth v1 2.0 sized 3 piece white wheels Top loaded grey body shocks with black caps. The body was team car style. It’s rare but not in the cool way. I don’t see it often on lists. The box looks like the CE box but the pictures matc...

But you are correct about the idle gear. The Worlds car had the bearings in the gear, with a separate axle. Non-Worlds cars and 10T trucks had a one piece gear with bearings in the housing. The world's re-re had the bearings in the idler gear but original worlds had the idler gear with shaft and be...

The C stamp chassis was, as mentioned above, available milled or plain. The milled version was a different grade alloy and was hard anodized. These are frequently purple by now. For the rest of my rambling here I will only be referring to the plain C not the milled. The early B and the late B had mo...

Do all original C stamps lack the counter sinking on the 6 gear holes? No, as I said most lack it but not all. By a different alloy does that mean the A&B were 6061 and the C milled were 7075. A, B, and plain C were 6061. Worlds milled C stamp were 2024. Were the nose plates also made different...

By the way, your screen name takes me all the way back to grade school. I signed all my grade school papers josephs.

I took the measurements from a new 6372 set and found these that match.

Looking at the B4/SC10 steering blocks (#9880), I noticed that the bearings were only slightly smaller than 5X10X3 mm bearings. I reamed the steering blocks with a 25/64 drill bit by hand. The fit on the 10mm bearings is tight. I also had to open up the center enough to allow the axle to pass throug...

For a budget hex conversion for trucks (haven't tried on cars), you can use the cheap and readily available parts for 2WD Traxxas trucks (Slash, Rustler, and Stampede). The front track width is slightly narrower than the Associated parts. All that is required is to open up the caster blocks with a 1...

Just checking, but did you zero the calipers with the depth gage. On my cheaper calipers, the jaws and depth gage don't zero together. It is about .2 mil out. My pic was showing a red line to indicate the inside surface of the hex recess, which is where I'd start measuring the offset, to the lip of...

Sorry, I'm out and don't have any definite plans to make more.

In performance on the track the Lunsford are probably no different at all but they are made from grade 5 ti, made in the USA, as well as lifetime guaranteed. Can you tell by driving the car they are better? No. But they are, at least IMO, much better.

AE changed the rear arms, it was a running change. You must have the early arms, so at that point I’d go for the kit that matches dimensions. The worlds will have the shorter pins.

This is all three sizes. The AE 6274 cups are 16mm OAL, 6mm wide, and have 9mm thread depth. These were recently discontinued but can still be found. The standard RPM cup is 20mm OAL, 7.5mm wide, and have 13mm thread depth. The long RPM cup is 26mm OAL, 7.5mm wide, and have 19mm thread depth. They a...

Replace them.

The ones from Custom Works are nice, and they retain the 4-40 thread.
