No problem! I don't mean to take this thread too far off-topic, but generally the pre-60s trucks were the "Pilothouse" and "Job Rated" series, "Sweptlines" and "Utilines" (stepsides) were built until '71, and "Lifestyle" (so named because of the packages offered- Adventurer, Prospector, Macho, Snowfighter, Warlock, Little Reds, etc.) ran until '93.
