"I think Metroliners, SPV-2000's, and "Amfleet" cars shared the same basic carbody. Kitbashers take note."
Very similar but there are a few differences. One of them is that the windows are taller on the Metroliners, though that is not a biggie. The biggie is the placement of the windows in relation to the vestibules, which will make modifying the bodies a little more difficult. You have to remember that Metroliners, like the Amfleet cars, are 85 feet long.
