I want to make sure I know this exactly. Is the diameter of a Flight II spindle 3/4"? It appears so when my little brain interprets the ticks on the ruler, but would someone please verify. Thanks.

3/4" or 19mm is correct, per Dan's Competition catalog.

you musta' double posted...see my reply at the other post.

Thanks guys. And sorry about the double-post. At the last second I wanted to check the "notify me of response" box. The system barked at me for that and somehow it got double posted. My bad.
