Here is a set of parts used to add detail to the MPC 22 Inch Eagle Transporter model kit.
These 'U' parts replace the ‘J’ clamps supplied in the kit to hold the engine bays to the upper gantry.
I felt that ‘U’ clamps would be more accurate.
Also supplied are some window frames that were painted white and affixed the the windows to avoid having to mask and paint. Various nuts and bolts complete the package.
I would suggest that these are only used in a resin printer and you will have to play with orientation and supports etc.
