Hi Doug Doty,
Your boat was made in 1958. Alumacraft made 1500 of that boat that year. http://www.alumacraft.com/About-Alumacraft.php?content=about_us If you go to this link and click on the 1958 Brochure you should be able to find your boat and page 22 will have all the specifications. I hope this information was helpful.
Thanks,
Alumacraft Customer Service Support
