Transmission & Differential - crx with b16a axle unsure.. help please

Hey guys, My 1988 crx with a b16a 5 speed, the axle needs to be replaced I can no longer drive it like it is and its my only vehicle at the moment

question is: Its already had the swap and it drove fine but the axle boot was ripped off and the greese spun out and caused the u joint to go bad.. anyway it would already have the axle it needed for the swap witch would be a 88-89 integra axle.. or is there something else they could have used..

Went to the parts store but I have no idea what to get so im kinda stuck

Look for a part number inscribed somewhere in your current axle. I'm not entirely sure if there is one, or where it is, but i'm willing to bet it's there somewhere.
