Newbie here stumbled on this thread while researching my '78 Toyota Chinook omega. You got yourself a nice one and you were smart to grab it. They are quite rare. My best upgrade was a Holley carburator. My hope is to convert to 5-speed transmission some day.
Are your windows glass or plexiglass? Do you know if they are original, or did the previous owner buy new ones? If so, what brand are they?
Windows are glass and original, not sure of make.
