I have a 99 gsr 5spd with a b20b engine swap, supposedly its still has the gsr tranny in it but they ripped the vin off so I have no way to check.

Well my passenger side half shaft went out and neither of the gsr or crv half shafts fit. The gsr half shaft wasn't compatible at all and the crv half shaft just wouldn't fit into the hub of the rotor.

if it helps the half shafts i've tried were 99gsr half shaft and a 97crv half shaft.

 

it's a b-series half shaft it will work....there's nothing special about a crv one vs a gsr one. the half shaft does NOT go into the rotor, that's the drive shaft that connects to the half shaft then into the spindle.

 

not sure why the gsr one won't fit, as all the passenger side axles are the same for a 90-01 integra with a manual. only difference was ABS or non-ABS. find another one.
