Wonderful
Thanks guys.
I will be running modern tires, but I have to tap into a box of mid-90's sets I still have in my workshop. That means some kind of schum yellows at the rear and some kind of studs at the front. Modern B4/Losi wheels seem to be a proper fit as long as the hole is re-bored to 5mm, I also have some 2.2 Kyosho wheels that would work too. Up front I will be using B3 wheels, 850's are a tight fit for the 5mm axle but it works.
We'll be running on a mix of carpet and linoleum, with ridiculous jumps. Tight and demanding tracks... very technical, I usually run my B4 with 8.5T BL mills, which is already quite a bit too much so HP isn't an issue... Check out one of the previous rounds here for instance:

(I'm the guy wearing the vintage RC10 shirt btw

)
I was planning on using the plastic yokes as I have a bunch... but not sure anymore now. I have dumped quite a bit of cash in that project already, might as well spend the extra $20 to make it bombproof.
Metal top gear is a PITA to find, even stock 21T top gears are a main hassle to source. Idler gear is much easier, even in alloy, as it's still used (or a very similar one) for modern designs. May I ask which one you call "layshaft"? The car also will have a brand spanking new diff and slipper assembly.
I will be running lipos as I'm short of proper SC's with the right watts, but some kind of 411P/G or HPC speedo (gotta check which one I have in stock...) and some kind of 15T or so mill to propel that baby.
Only parts non new on the car are:
- shock bodies/pistons/shafts
- tranny case , top gear + rear batt box
- both shock towers
- steering bellcrank
I'm really looking forward to that race and I'm counting the days till the 20th... thanks for any help you might have!
