I remember how Gambler used 4 digits in there serial # back in the 1980's etc. What would a five digit serial of 90088 tell you about a car?thanks

My guess would be the 88th car built in 1990.

That was my hunch also.

Floyd at Bailey Chassis in Hendersonville, TN could give you a definitive answer. He ran the shop at Gambler for many years.
