These are what many high $ boys run;
Its not a Ford 9 inch but its based on them, and I believe stronger than the Currie versions.
I have seen a number of low pinion Ford nine inch diffs home converted to front axles, however the lower pinion sometimes gives even more problems in the front than it does in the rear due to it off center location, on long travel suspensions.
Most of my friends have gone beyond the (light duty) D44/35 inch tire, stage and are at least running 35 spline (Chevy for passenger drop fronts or Ford for driver's drop) D60s in front.
If you want a Currie rock Jock high pinion front (they are way better than a D44 (if used with high spline count 1.5" axle shafts); the iron center sections are relatively cheap and relatively easy to retrofit with stock 3" or 3.25" tubes; IF
you are an experienced
Note; most D44s came with smaller tubes but some are 3".
Be aware, however, that the rock jock centers are not a good candidate for conversion to Dana 70 gears (the stock Ford D60 high pinion center section is a better candidate for this, IMO)
