The Tamiya Shocks are from
here
And the Black hardware is from
here
They fit right on, Just use with TC6 (not TC6.1) shock ball cup bottoms with a 1mm shim before your screw it on. Total shock length 63mm.
The TC6Tek Chassis has holes for both the standard TC6 steering system and the upcoming Exotek one.
Yes Tamiya blocks will work with this car.
Cheers!
