Hi everyone,
I plan to "upgrade" a defective vintage audio amplifier with two class D, preferably TPA3255 boards. In order to use the existing heatsinks I would require a board that has the TPA3255 chip mounted on the bottom side, sort of like this one: https://www.diyaudio.com/community/threads/tpa3255-core-pcb.343919/#post-5945395
Do anyone know of such a board?
Thank you and kind regards!

The TPA3255 boards from 3e Audio appear to have their amplifier chips on the bottom side. However, they are also higher than 6 cm. Perhaps the electrolytic capacitors can be replaced with ones that have the same capacitance but build lower....?
Not exactly what you are looking for, the heatsink is at the top. But it is low profile:
