Jeff, I laid the mount on the floor and measured up to the mounting pads. This mount has right hand and down thrust built in to it. Looking at it from the top the upper left pad is 9" the upper right is 9-3/4" The lower left is 7-3/4" and the lower right is 8-1/4" The distance between the firewall mounting holes, upper is 33-3/4" lower is 23-7/8" all measurements are approximate, kind of hard to measure. Looks like the distance from the firewall to the attach points is about 8-1/2"
