Adam and Shaun, I'm just wondering whether these are simply the ones sold by Taigen? If so, I noticed that one contented Forgebear customer noted that he had fitted sets to three of his Tamiya Tigers.

However, on Rcuniverse, a contributor stated that it was necessary to Dremel the axles to fit, as they were a tad too long.
https://www.rcuniverse.com/forum/rc-tan ... heels.html These were branded Tamytam.. but look the same as the Taigen/Asiatam ones.
That, in itself, would not be a problem. The diameter of the axles would be crucial.
Undersize, relative to the existing Tamiya arms, would require bushings. Oversize would require drilling the Tamiya arms out slightly. All do-able, yes, but a fair amount of work and swearing. Oversize would be easier to deal with.
I must compare a Tamiya axle to one fitted to the Taigen late model.

That'll be the sensible recce approach

Anyone have the relative dimensions to hand?
I see that Dominique has Guido's wheels for sale (I assume they're Guido's), even though his website lists them as 'ausverkauft' (sold out).

highly desirable, yes; but at that price, I'd have to to sit staring at them for weeks on end, to fully appreciate and relish their qualities, and then justify such a whopping outlay.
