According to the Osborn assembly manual, there are 2 different battery trays for a 68, one for a car with the RPO 55A battery (?, I think they mean 55A alternator) and one for eveything else. They list a -A and a -B tray, both 68 mustang part numbers. My car has the "heavy duty battery" option and shows a 55a alternator on the build sheet. It came with the C7ZZ battery heat shield as its still present. Unfortunately, what was left of the original battery tray was inadvertantly disposed of so I have nothing to match up.
It seems that currently there is only one battery tray offered for a 68, and one size battery ( a group 24). Can anyone shed some light on what the difference was in the two battery trays if they are both for a group 24 battery ?
My car is a very late build Metuchen GT Fastback, 390, 4 speed, AC car (built July 18, 1968)
Thanks in advance, John
