hello. i'm a newbie when it comes to these cool old trucks. i just purchased a 65 c10 stepside with a 283 about a week ago. it's been sitting for almost 15 years so i'm going to make an attempt to resuscitate her. i'd like to get some additional information with the "custom" sail panel. what is the difference between a base and custom? i've seen the fleet side custom with the side molding, but can't find any info on the stepside.

thanks for your expertise...jc
