OSCAR Late Model NASCAR Tips

Everybody knows the 1/24 Chevrolet Slab Side bodies are the best for the OSCAR Late Model NASCAR Class. But the question that always comes up is; which ones are the Slab Sides? The Slab Sides are the 1995-1999 Revell Monogram Chevrolet Monte Carlo 1/24 kits. But they were not all slab-sides. You have to check picture on the model box to verify. Some of those years, including the Luminas had curled sides too.
