TR6 Does a 75 amp alternator require a wiring upgrade of any kind?

I am tempted to get a 75 amp Bosch alternator which BNR on eBay says is a direct bolt on. BNR comes with praise from others on this forum and they have great feedback. The alternator is here: https://www.ebay.com/itm/Triumph-TR7-TR6-Alternator-Generator-Bosch-75-Amp-For-Lucas-/350920590829

My question is do I need to upgrade any wiring in the car; specifically the main "brown" charging wire from the alt to the battery/starter block? I'd really don't want to do this because I don't want to rip up my pristine wiring harness on my 76. I don't want or need to power very much - there's no electric fan, driving lights, or high powered stereo. The car is stock.

Thanks!!!

The stock wiring should be fine, given that you aren't really going to use 75 amps, except maybe for a few seconds right after a cold start.
