Aftermarket manufactures state a rubber compound difference between the two, guessing due to balancing/torque differences?
Possible indeed. That said, knowing Toyota, I'd be ok running either. If an option was not an option.

Logic dictates that the 13BT variant would be "heavy duty" because of the additional torque produced over the 3B motor.
But I could be way off.....

So should I get 13B-T mounts if I have a turbo 3B?
Logic can be elusive when it comes to selecting (designing for) the correct vibration isolator for each application. As CruiserDan has identified, torque of the engine is probably a key performance parameter. However, so are mass and inertia differences between the 3B and 13B, structural stiffness of the vehicle frame, stiffness/dampening of suspension springs, ... and most likely other parameters that I am not thinking of. The dynamic response of the entire vehicle (system) could be driven by the dampening characteristics of the engine mounts. For example if the dynamic response spectrum of the engine/driveline is relatively close to a natural frequency of the entire vehicle system, then the stiffness and dampening characteristics of the motor mounts becomes very critical. Hence, small differences between very similar engines like the 3B and 13B could yield major vehicle system dynamic responses. i.e. Unique motor mounts are required for a 13B versus a 3B.
Sorry about the weak explanation. I don't dive into dynamics and flutter considerations on a regular basis, so I am very rusty on the topics. Other members that design and analyze isolators & mechanical dynamics on a regular basis could provide a better explanation.
Front hub wheels studs are available...
Toyota part # 90942-02053 are available from the dealer
Napa Auto Parts # 6413126
Dorman Part # 610-264.1
Those who search this thread may be disappointed as the availability through US dealer channels is changing daily. 70 series are a dirty words to toyota these days.
Wonder if it's because cruiserheads are affecting procurement forecasts and warehousing requirements calculated for the mining industry...?
