If my camera wasn't broke, I'd post a photo, but here are the measurements:
Heater Base: Front to Back 14.375"
Side to Side 9.125"
1" Lip to Mount to Fender
Vertical Upright: 12.5" Up and Down
8" Front to Back
1.75" Lip Mounts to Frame
2.125" to 1.5" (Tapered) Mounts to Heater Base.
Post again if you need a better explanation (it all makes sense to me,

)
