Custom driveshafts?

[1986stangfan]

Hey all, it’s been a very long time since I have purchased a custom driveshaft. I used to always go to Dwight at driveline in whitby, but he has sold the business so I hear. Looking for suggestions, the wagon will make around 850-900hp once the supercharger is installed.

Any shop recommendations?
What materials do you recommend?
I’m leaning towards carbon.
