72 Core Support differences - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey guys, my truck (Rusty) has the AUX battery option but the AUX tray was welded to the core support, guessing because there are no mounting holes for the tray. I bought a core support from an AC cab 72 that also does not have the AUX mounting holes.

What is an easy way to go about adding those? The standard tray has welded in nuts on the core support and i dont think there is an easy way to go about that again.

Also, should the AC core support be different than the non-ac?

And for a dual horn truck, should there be more than one spot for the horns to mount?

If there are any pictures of any of this that would be great as well!

Ac and non ac core supports are the same. The main battery tray is different for ac and non ac.

If the old aux tray was welded on, why not weld it on the new support?

The horn nut mountsare already there. I have found that the low note is mounted close to the radiator and the high closer to the headlight. I parted a 72 highlander a few weeks back and pulled the core support with factory dual horns. Sorry no photos at this time.
