The 5310's must have been a Ny only model Other final series 40' new looks wee 5308's
Where were the 5310's used and when were they built?
As for the 35 footers you are all correct.
The 2 door transit 35' new look buses were 4517, 4519. 4521. and 4523. Over time I have had the honor to drive buses in each of the series.
Madson Metro T6H-4517 #227 was my favorite new look. TDH-4512 #213 was better yet. She was a clasic.
