The door, glass and mirror are assembled so I can't get an exact measurement, but it looks to be around 30 inches.

Once I took it out of the downward-pointing bracket, I had plenty of slack. I'm pretty sure if I flip the bracket 180 degrees (point it up) everything will work fine. Hoping someone can confirm. I'm gonna dig out the shop manual and see if there is a diagram.

Until total honesty is on the table, we're not even talking about reality...
