Diff help...
I have a '91 f150, wAs looking to upgrade diffs to something with limited slip.
Currently has the 3.55 ratio, axle code 19, I believe it is a 9" but never really looked yet. Will the 4.10, axle code B5 (preferred) or H5 diff fit in the hole?
And is the front diff with axle code H5/B5 also posi? Or just 4.10 ratio?

Ok here's what I've learned so far:
The "1" in the code 19 means 8.8" axles
The "9" in the code 19 means 3.55 ratio
From that I gather the H5 code diff will bolt in using exsisting axles
To go to the B5 code I will need to swap the axles to make it work.
Will the B5 swap require other housing for bearings to fit or can you just swap axles and bearings into the stock housing that comes wrapped around code 19 setup?
I really wanna dig all four down to the axles, rather than the two that seem to chew away now!!
