Denso Alternator Installation

I'm running Edelbrock 6017 heads and with the Mancini bracket kit, the John Deere alt was a no-go. She bolted up, but the additional mass on the back interfered with the head and there was no room for tension adjustment. I just went to the parts store and picked up a 70amp for Hilux, oh well. Anybody want to buy this 120amp little guy??
