I'm thinking about putting skid plates on my 78 F150 and wanted to run my idea by you guys first.
For the d44 front dif, I was just gonna weld some thicker steel to the cover to stiffen it up a bit. I think 1/4" should be enough to keep it from denting in when I hit big rocks.
For the 9", I want to come off the bottom carrier bolts, wrap underneath, up the back and wrap over the top down to the top carrier bolts.
I think the front might be ok, but I wouldn't do that on the 9" for a couple of reasons first you will be providing a place for mud, and water to collect causing rust, plus the flex in the iron will cause the plate to wear on the back of the housing, and finally 9" diffs arent real bad about hanging up but if it was me I would just build a wedge plate that bolts to the bottom of housing (weld a bolting plate to the underside of the housing, or bolt it on) and bolts to the pinion support, or just leave the top end loose and bent up around the yolk.

That is more like a bash plate and not a skid plate. All that will do is push in the cover where there is not any 1/4 plate, the weakest point. If you are worried about holing the cover, then make something that bolts on the axle tube and covers the front on the lower edge and wraps around the bottom that will protect the lower bolts too.
No idea on the 9", never built one for that. Though James Duff has some nice stuff if you need ideas.
