Denso Alternator conversion Part-Number ?

hi, yesterday my Voltage Regulator quit working, so i´m thinking about going the Denso-Way and switch the old Mopar Alternator against a modern Denso with internal Regulator.

i guess this was done by many Mopar-Drivers before...and so i wanna ask, which Model will fit best or if anyone cld provide me a part number (v-belt groove prefered, as i don´t like to hassle around with changing pulleys)

thanks
