Will A "Yellowstone" Shell "FIT" on a PS1 Big Boy Chassis?

Hello, Anyone have any ideas about this???-Thanks

I doubt it very much.

Kenny, grab your MTH coin and rub it.....now, repeat after me: "I wont murder the big boy" …….LOL!...

It's a big gamble if the shell will fit the chassis. Most likely not. I would pass on this one if it was me.

No, the shell will not fit. After careful measurements, it is clear the several key points will not allow the shell to mount without modifications. The big two are the smoke unit and rear cab stud/mount.

Have had my PS1 BB apart several times for upgrades, smoke, etc.  It is a very close fit with it's own shell to lower frame.  Have looked at, but not owned a Yellowstone.  Really doubt the two would line up and fit for proper running.  MTH was not known for mass producing scale engines and simply changing cosmetics to "look" like a different type engine.

Thank You Everyone!!!  I sincerely thank you all for the advice. If anyone else is in need of a MINT Yellowstone Engine Shell and Tender Shell,complete with the lighting,I can pick it up for you for $175.00 for both. 

I told you it wasn't cheap,but when is the last time you even saw a Yelllowstone shell for sale period???

This is  MINT from the factory,which is why I was getting that "Maybe I can use it someday" felling about them. I still might pick it up and do a mod of somekind with it,but that seems kind stupid to ruin a MINT shell to make a TRAIN ROD!!!!

Stuff 3 big Pittmans in it,5 smoke units,Repaint it with Lacquer Candy Apple Red,(with big flakes),A Six pack ,(always) hey wait...that 6 pack is what made me think of doing this in the first place!!!!!!

But seriously,thanks to everyone for your input.You just saved me $175.00

Thank you-Kenny
