FE alternator mount

[Gunner]

I am beginning the process of pulling apart various assemblies on 707 to remove corrosion (it lived near salt water in its prior ownership), replace fasteners with stainless and/or ARP, and to powdercoat various bits.

I am looking at my alternator mounting and trying to figure out what's going on. It's a standard Ford-style alt with a Ford VR. The top bracket appears to be the grey powder-coated or anodized one provided by ERA.

The pivot mounting... is weird. There's a powder-coated base block bolted to the head, with what looks to be a long pivot stud for the alt. At the outer end is what looks to be a piece of flat steel bar stock running from the pivot nut to one of the water pump bosses. It's uncoated and rusting. There is also a piece of similar bar stock at the inner end of the pivot, near the spacer, running to another bolt or boss on the rear of the water pump. (I know, a pic would be helpful but bear with me.)

None of this looks like any standard mounting I've ever seen. I suspect it's a combination of ERA pieces and some inexpensive fab by the original owner.

Is there any reason a standard Ford FE bracket would not work for the outer brace? Is there any point or purpose to the inner brace, given that the mounting bracket is very sturdily bolted to the head? I'd like to dump the inner bar and replace the out with a standard bracket, but I don't want to buy a bracket only to find there's some reason it's not used in this setup.
