Commercial Chassis Dual Battery Tray Questions

I'm looking for some info and hopefully some pictures on the commercial chassis dual battery setup. Is the second battery tray (driver side) , the same as the passenger side or is it mirrored? I'm not near my car for awhile or I would look. I'm looking in to doing a dual battery setup and looking at options. Thanks

I have not seen a setup like that.

This was not on any of the 4 1964 Series 75 (6723 & 6733) I pulled in and parted during the day and not in the 75 series literature, but Commercial Chassis (6890) Cadillacs went out to coach builders who I could see installing a 2nd battery for the extra electronics, especially for an ambulance. I would check with the guys at the PCS (Professional Car Society) and see if they have literature with dual battery set-ups for particular coach builders.

1963 RHS A/C kick panel - photos needed

Posted by SK on June 2, 2025 at 2:20pm 2 Comments 0 Likes

Could someone post front and back photos of the 1963 right-hand kick panel with A/C?

My car didn’t come with the original kick panels, so it's a bit of a mystery to me how I should cut the backing board and carpet to fit around the A/C.

Many thanks,
