I know wiper arm replacements have been covered several times here but I can't seem to find anything that looks the same as ours. MOT replaced one side a while back. I'm sure I could just call them or FOT and get another but would like to avoid that. It seems like all of the ones I have seen posted the splines that drive them are a different size than the idle one. Ours are both the same size.
Try busparts.com see if they can help. Or just search school bus parts you will find plenty of wiper arms and blades.
Maybe this post from Tulsa Trent will help.

Thanks Bruce and Dave. I'll check out busparts. I had seen Trent's post about that. Looks like he changed out the part that drives it also. Which probably wouldn't hurt anything since they're 20 years old. I did find one that looks the same as what I've got on eBay. Durite was the brand but the only place I can find them is in England.
