Olthoff's sells the shoulder harnesses that go with the lap belts. Stock SPF takes a Y-type harness, which isn't legal in some - many - racing events. I've been meaning to call him since I saw him at Barrett Jackson. Guess I'll do that soon.

You're going to need the seats out and the tunnel opened to install the engine/tranny/driveshaft. Unless you want to do it the hard to impossible way. Few SPF owners install their own drivetrains, from what I hear, but I found it to be enjoyable, and had a great "helper"...truth be told, I was the helper LOL!
