I'm currently in Afghanistan and will hopefully be home within a month. I already have my 5.3/4L60E waiting to put into my '64. From what I've read, the actual engine swap isn't that bad. What concerns me is how to make the new tranny work as in, how/what do I need to do. It currently has a 3 on the tree and I want to still have the gear selector on the column. I would assume I need to get a different steering column? Any help would be appreciated as I will have little time once I get home. Heading back over here in August and would like to get the truck on the road prior to leaving again.
