Part 2: Fuel tanks to one of the AMT semi trucks white road boss or movin on etc.. each tank is 2 halves and they are laid end to end to make up one side of the two number 2 parts.
The nacelles I have are 8 1/4" long and taper from 1" diameter at the front to 7/8" diameter at the rear. If those parts are the nacelles you would need the outer half as the inner one has a trench running down it.
