I agree with Thomas,

The roadster wiring harness was adequate for the stock alternator, rated at
30 amps, closer to 24 amps real output. 

Take into account the 8 fuse late model is adequate, earlier models are
even less adequate.

Without perfoming a few critical mods, just bolting in a 45+ amp alternator
and a couple wires could be dangerous to your wiring. It also could shut
the car suddenly at night when you least expect it.

These mods should involve multiple fusible links and/or breakers, fatter
wires in some places, better grounds, and potential bypass headlight lines
for safety (if critical circuits are controlled by a fusible link).

Age and increased load makes many connectors inadequate for the current,
cleaning may work in the short term, but replacement with gold will stay
dependable in the long run.
