1936 Hudson Custom Eight, length question

In the process of buying a wiring harness for my 1936 Custom Eight,model 67. Wire harness supplier has specs for a 1936 Deluxe Eight. I know that a Custom Eight is 7 inches longer than a Deluxe Eight. I am trying to figure out where in the chassis they made it longer, was it between the cowl and front of the car or from the cowl to the rear.

Thanks for any info
