[1960HDGMC]

Hello, I have a 1960 GMC Model 1002. The Battery Tray was for a 29NF Type Battery. Is this standard? When did the 1960-66 GMC trucks switch to the modern footprint battery tray? I had to modify my tray to accept a modern footprint battery. Will a newer tray designed for modern batteries bolt right up where my 29NF tray is? I run an Optima Yellow Top Battery, because it is the best battery I have ever run up on. I do not want a Billet anything on my truck, but I see they make a wrap around hold down for the Optimas. Has anyone ever used a 1957 era GM wrap around (painted stamped steel) type hold down with one of these factory battery boxes? it looks like it would work and look clean too. Any factory or modified battery box pictures sure would help. Thanks for any help, Greg Mead
