I have a ZF5 with the 460 bolt pattern to put in my IDI. The trans is disassembled and I have new sychros and bearings to put in it, so I can stand the case upright to work on it. I have an adapter plate off of my old engine to use as a template. The 2 top holes needed to be opened up for the bolts to fit, so I did that then bolted the adapter plate to the trans case to use as a template. I am thinking that the holes for the dowels need to be pretty exact as to not put a side load on the input shaft/ pilot bearing. With the bolts backed out 1/2 turn, I can move the adapter plate around a little in relation to the case. At the dowel holes I can get about 1/4" variation on the spot to drill. Should I just center it up, take a leap of faith, drill it and hope for the best or is there a better way? Any other input for this conversion greatly appreciated.
