Builders http://www.autoworldstore.com/product_p/amt1005.htm Hobbylinc has two of these kits with different part numbers. What's the difference between AMT '56 Chevy Nomad kit 1005 and 1005-06? The 1005-06 is less money than the 1005, wonder why? Same question about all the other kits with an extra number on the end. Been wondering about these AMT part numbers for a long time. Thanks!
