I’ll agree with using the Revell kits. You’ll get a more detailed finished build than the MPC version. Grille and taillight panel will be interchangeable between the 68 and 69 kits if you don’t want to deal with the vynil top on the 69.
Got these in last week. The Galaxie will be used with a 4 door resin body from SMH to make a Mayberry patrol car. I thought the trucks looked cool and would be a couple of fun builds.
