Is there any physical size and fitment difference between a 78 floor panel and a 74? With expception to the little troff thing that was added under the accelerator pedal on a 78? Reason being i got my hands on a 72-75 RHD cab floor repair panel and was curios if it would fit if i just added that troff for the accelerator?
I am pretty sure they were all the same throughout the bay range. Best thing to do is compare it by offering it up if you are unsure. The pedal cut out will of course be the other hand.
