Roll Down Rear Window Drip Pan

[Bud]

Hi,
I have a drip pan for what I believe is a 1932 Coupe Roll Down rear Window. I collected it years ago when I thought I would put a roll down rear window in my 1930 Deluxe Coupe. How do I tell the difference between the Model A version of this part and the early V8?
One thing I did note is that the three attachment holes per side are evenly spaced at 2-3/8" apart (D-nuts) whereas it looks like the Model A version is unevenly spaced.
What would a V8 part be worth?
