I'd like to come up with some way to use the (modern) Chevy battery hold down frog that is a one bolt (near base of battery) retainer. Makes R&R battery a lot faster and eleminates the metal bracket at the top and greatly reduces corrosion of the battery retainer and cable interference/shorting possibility.
The foot print of the GM tray utilizing that means of retention may exceed what is available in the OE Packard tray. GM trays are also sized to specific group sizes of battery. You may have to scratch build one.
Also, the battery case must be specifically notched to accept not only the one GM retainer, but two tabs on the battery tray.
Even then, corrosion of the stamped sheet steel battery tray was still a problem on GM vehicles.
Personally, I think it takes less wrenching to simply loosen both j-bolts and swing them free of the notches in the tray rather than completely removing the single bolt on GM vehicle, which is necessary remove that holddown, which is necessary to remove the battery.
As far as shorting, you only have to worry about one cable, and I've seen rubber hoods that go over the battery terminal/clamp.
