This is the one I used on my '72. I'm pretty sure 65's had 2-1/4 in. wide leafs like the 67-72. Maybe someone will correct me on this. As far as a notch goes, I needed one, but I also pulled some leaves. Just depends on how she sits now. Just picture your axle sitting on top of your leaf pack and add an inch. If you do order this, type in SHIPME in the checkout, you'll get free shipping! Sorry to hear about the layoff. Times suck all over.
