I'm using a Strange steel shaft in my car. I used several Inland Empire Driveline shafts in customer's cars over the years. Denny's and some others are nice too. Aluminum is nice, but more expensive. Go with the 1350 joints. You'll need to swap the yoke on the rear end and get a new one for the transmission, but it's worth it. Be sure that it's high speed balanced. The M20 won't hold up to that much power if you use slicks.
