JFP, Thanks for the rapid response. I'm going to take it out for some laps around town on the bypass tomorrow, 50-60 MPH as you suggested.
The AOS actually went in very easily. I disconnected the oil filler tube, next to it up top, and the mount for the O2 sensor below and beside it. With cable hose clamp pliers and positioning the clamp in an easy to access position, it went right on first try.
There's no emission inspection here in Oklahoma, but still it's a nice car and I want to keep it correct.
