ATTENTION: The glassBYTEs.com forum is being retooled and will return with a new look and functionality that will hopefully help our readers even more. Watch for an announcement when it will be ready, it will be a few months.
You can still stay up on daily news and comment on stories by signing up for the glassBYTEs daily e-newsletter at glass.com/subcenter. There is no charge. Hope to see you there!
Answering my own question in case anyone is curious. I just ordered one to compare, they are the same part besides the dw2038 having a larger paint band. One is for a Peterbilt and one is for a Kenworth but you should be able to interchange them.
You really have to inspect the truck. Some Peterbilts have mirrors that come up from the sides of the hood. the larger black band will make the mirrors hard to see (safety issue). We learned this the hard way!
