Not talking about the gauge, but look at the lug strips used in the chassis, and if they used solid wires or stranded ones.

I mention this as, when I started to recap/rewire my 47-1230, I got stranded wires of appreciable size.
Appears the type of lug strip used in it works like a charm with solid wires, and is a bit more iffy (but still very doable) with stranded. They are sort of T-Shaped lugs, you simply twist the solid wire around, heat, put solder, and are done. Stranded don't hold that easy; so I would have been better to get solid ones while I was at it; and the price was about the same (maybe even cheaper if I recall)

But as long as your wire is big enough for the power passing trough it, you're all set. The rest is mainly cosmetics.
