I probably bought wrong 8 3/4

Geof, thanks a mill for your help. I live in CA but grew up in Jackson and my family has a cottage near you at Strawberry lake. My best childhood memories are of tooling through the Pinckney chain of lakes. I guess I'll start looking around for a '73 Dart Swinger driveshaft for starters. I was going to just put this single axle in to complete my powertrain because I don't plan on running it hard and we don't have snow here but with me now knowing how unique my 8 3/4 case is I have to go whole hog and make it a suretrak. From what I'm hearing I better take on a second job to pay for it.
