Measurement for a driveshaft

[Jesse]

I'm trying to get a quote for a driveshaft for after my SYE kit. I am not sure what length to order it or even what length to get it quoted at. I measured my current one using the picture on Tom Woods site, but that didn't help much. If I'm not making sense, just say so. I've attached the picture from TW site that i used. Any insight as to how to know what the final length will be or what length I would need?
