i know this thread has a few cobwebs on it but worth the dig. i had the same problem before xmas, and seems a few others may have also as all the U12/UA wrecks i came across had the wipers missing. i found the best solution was one from an S13. although you will need the entire assembly even arms as they are 14mm bolts. you will have to re-drill the blot holes a bout 5mm L&R, and may need to grind the bolts off. the arms are also alloy. i have also ordered one from nissan as the one i found has a hairline crack for $80. they are the best substitute and parts are still available from japan.
