What is the exact fin dimension for the bottom fin on a 1959 Rocket fiberglass boat manufactured in El Monte CA?

I just purchased a 1959 Rocket from a friend that had just about finished restoring this boat, but I will not be picking it up until Oct. Will check out the bottom fin when I pick it up. Does yours have a V-drive and Corvette motor? I plan to finsh the restoration and then show it behind my 1955 Chevrolet Nomad. Would like any info you may have on these boats. Thanks, kgwatts@pacbell.net
