Well mine is definitely too long by a couple of inches. Maybe it is just made that way. I brought it straight down and then circled the inboard lower mount leg (14A). It has the feature of going exactly halfway between the exhaust pipes like that instead of rubbing which is what it looked to do coming straight in. Will place an adel on it to keep it off the mount leg.
I also found that the bolt supplied by Airflow Performance for my mixture arm was too long to install with the nut between the arm and engine as showed in the pics. I reversed it with nut down and operates fine that way.
I've also got a whole bag of brackets and nuts/washers that I'm not going to use because of not using the Van's stock setup. Oh well; I needed just a couple of things out of it for the governor cable. If I was ordering again I'd omit the Van's cable part bag and buy the rod ends/washers/etc as loose parts.
I'm also super happy with the way the SteinAir custom cable control panel looks. It is super sturdy. I put masking tape over the part while I drilled the holes up to size.
