Got a ? about a 14BFF swap in a K2500

[Thunder]

Going to do a axle swap in a 91 K2500. It has a broken 14BSF in it now. Got a 14B FF out of a 92 K2500 I want to put in.
Is this pretty much a direct swap?
Will I need diferent rear U joint or any other parts?
Thanks for any info you can give me. Just tring to have everything I need together before I do this swap.
