I'm using the Con-Cor U-50 chassis, some careful milling on the sides and end will need to be done for snug fit of body. Mill down slowly and check often so not too much will be taken off. This Propane Turbine also used a custom made pressurized tender from a 17,000 gal tanker. For all detail on both builds I did a search for HO brass Propane Turbines. There will be every picture you will need to build it exact as per prototype. This is just one picture among many that you will be able to get all detail. Actually, this will be a fairly easy build on both, just will take some time mainly on the tanker tender build.
