So...I came up with a few different solutions to this, one being to mount a stock reluctor to my crank pulley and use an external pickup.

Another being to take a 24X reluctor from a BB Chevy and mount it on the crank snout behind the timing cover and install a sensor bung in my cover. This can concept certainly can be done and would be clean looking being that it would be factory style....but I chose to go with the easier external reluctor for now.

So, I took a stock $22 reluctor and removed just enough material to make a snug slip fit on my stock tapered crank pulley. The key here is alignment and indexing. I wanted it to sit behind the pulley, but in front of the balancer. Also I had set the motor at TDC #1 and marked the pulley to line up with the sensor location (using AndyF's bracket) before I removed it originally. Then, I just tacked the reluctor in place once I had alignment and indexing correct.
