Hello, I have a 1969 plymouth fury III,it has a round back single field alt, but now when I bout new alternator today the only have square back with 2 field, I was told to ground on of them to alternator case, is this OK to do , also the tested specs on this unit is idle 47amp and max rpm 79 amp, I have the original battery gauge in the dash, will this alternator cause issues being hooked up to original charge wire, thanks on advance for all the help.
