Though, the reason the Classics Rodimus redeco as Side Burn worked in the first place was because of the exposed engine he had on his chest like Side Burn's original toy. Looking over Hot Rod's toy history, that toy and the Titans Return Deluxe are the only Hot Rod toys that have that feature.
The SS86 mold would just be Hot Rod wearing Side Burn's colors, like how Super Side Burn is just Side Burn wearing Hot Rod's toy colors.
