So the assembly continues.
Assembly of the rocket frame does require concentration and removal and clean up of each rail individually before assembling the part and then starting on the next one. The parts are different and need to be assembled in the correct order. The plastic is resistant to my normal Humbrol Liquid Poly.
The rack can swivel from side to side (only a small angle) and can be raised and lowered.
The only part that is shared between the two optional load beds is the spare wheel. I used the kit item on the MRL version as it is the most obvious.
I used one of the spare wheels from the Rubicon Allied Stowage set on two pieces of 0.30" square plastic rod for the cargo version. Be careful that you do not mount it too high otherwise it will interfere with the fitting of the load bed.
And here it is fitted to the chassis.
