Hello everyone, I’m new to the forum and need some help. I purchased a 64’ & 71’ Landcruiser FJ40 and also received a extra transmission/transfer case with what I’m told is a rare Hone-O-Drive overdrive unit. Overdrive unit is not labeled Hone-O-Drive like other units I found online. Has the numbers 2962 on main housing, 4001 on tail end and A4118 on linkage circle. Can anyone confirm what this is and model. Any help would be greatly appreciate. Thanks, Drew
