7.25 sure grip

I'll confirm this later after I finish dismantling the truck, but early (87-90 or so) Dakota 4x4s use a 7-1/4 front diff and I believe it is a sure grip unit, after I get to pulling one out of the truck I'm tearing apart I'll see if it's a sure grip unit and check if it's spline'd to accept solid axles as 4x4 Dakotas had CV's. After that it'll likely make it's way to the classifieds here lol!
