I'm looking for a Hot Rod G1 authentic toy compatible with this scale, at a basic estimate, 14-15cms in height:

Preferably with a 5mm post grip so he can hold Firebolt as a Targetmaster should.

The toy can be either official or third party, either manufacturing source will be acceptable as long as the design specifications are quality and compatible.

And to be clear, Hot Rod, not Rodimus Prime.
That apparently confused the internet a lot, which didn't know the difference between the two.
