At the top of this thread John Gibbins highlighted the problem of shorter repro flanges, but with no measurements. As I only have what I have, I cannot be sure whether mine's too short (if you'll pardon the expression). How long should it be?
John also recommended tightening the castellated nut to 180 ft lb. My 'professional' torque wrench only goes to 150. Why so high? What happens if it's less?
What came out (probably French Hotchkiss) and what went in (new part from Tony Sudds) are the same size, so I have no way of knowing.
Here's a pic with dimensions:
How does this compare to your original longer flange?
