Ford Mustang V6 4.0 L automatic cardan shaft

Hello together Question: When lifting the speed limit it is necessary to install a new cardan shaft made of aluminium. The background is clear. My question is, is it possible to install a cardan shaft made of a GT in a V6. The speed of the GT is limited to 230 km/h.? If not where do I get a cardan shaft (Aluminium) at a good price? Best regards Hugo
