Well the wiper arm saga has come to an end. After talking to several parts companies on the web... I finally found one (locally of all things here in the Fort Worth area) that has got me what I needed.
Turns out this wiper arm was a hodge podge of a couple of things. Its a press on wiper that was drilled out so that it could be mounted on the pivots. This is why this has been the biggest pain in the ass.
Here is the old and new wipers......
I would like to encourage every one to use this business. These guys worked for over 3 weeks to find what I needed. Here is the web address http://buckswheel.com/
I walked in their warehouse and its packed with TONS of items ready to ship. Some of them for much older buses like mine (1983 model) so I can not say enough good things about Rodger and Sandra there. They did an outstanding job.
Ok on to the exhaust to get that fixed so I can get it legal on the road again.
Thanks for everyones help on this issue.
