Recommend you browse the Bowser web site for instruction sheets. The sheet for H21/H22 lists part number 74090 as a "crown" truck. 74091 is for a pair with wheels. I think this is the 2D-F8?

NO!!! The The PRR "Crown" truck is a completely different truck, class 2E-F2 Nothing at all like the 2D-F8 truck!
