12563532 has a cost of about 35.00. I do know that there is a difference in the gen 1 style and the gen 3 [5.3] style convertors and the length of the input shaft. I put an older style 4l60e in a 5.3 truck, it all bolted fine but the converter was pulled so far forwad that it poured oil from around the input shaft seal. So, I would assume thats where the spacer would come in handy. Jim
