I changed my positive earth to negative , it's quite easy.

The benefits are , 1st you can install an alternator which are all negative earth , you can fit modern radio / audio equipment if you choose.

But you have to re-wire the tacho , internally other than that i think everything else works.

And your window control switches will work backwards until you reverse the wiring on the back of the switches.
