Just copy and paste the link, but I have to go to HTML every time I want to post a link. I think I found it though:

Yep, it looks like the other Cummins parts come from all over the world. Too confusing for me to get it clear.
I've been trying to find what MCI did to downgrade the D4500 when the went bankrupt. The original D4500 was the same as the 102DL3, it was renamed in 2001. It appears that MCI changed from a riveted to a bonded roof in 2004, the year they went bankrupt. That was also when MCI changed the name to D4500CL. Soon, in 2005, they came out with the D4505 and around that time, the D4500CT as well.
The D4500, D4500CL, and D4500CT all use the 102DL3 VIN prefix, 1M8P, but the D4505 uses a new prefix 1M86. See YARTS fleet list:
http://www.yarts.com/rfp/2012/ExhC%20Fleet.pdf. Those say "D4500" but are actually all D4500CT.
Currently, the D4500CL and D4500CT are offered, the former "unofficially", in that it's not posted on the website, you have to order it to get it. They both have the bonded roof like the D4505, but are also available with the rubber bumpers, fenders, and thick rub rails carried over from the 102DL3 which are advertised to be more durable than the same components on the D4505. The problem is, they still only come with Cummins engines.
Here's a D4500CT in Golden Gate Transit service:

I like the GGT livery, but don't know about the red wheel hubs, though I guess with red Cummins engines, it somewhat fits the whole deal. And it does sound just like Greyhound's Cummins-powered D4505s.
