@dat521gatherer I assume you're referring to the lovely rust patina ;)
I need the lower hose (Part No. 46212-20500). I spent some time today trying to find something that would work from local shops, but clearly didn't have any luck. I've also heard that you can fab one with the fittings, but I'm not sure where to go for something like that. I called around a bit, but It seemed like the problem was finding a tube with the proper diameter.
I also found that the later production Datsuns might have used the same hose, but with a different part no (ie. 46201-89912). Thoughts?
I really want to get my truck back on the road. Thanks again for helping this amateur out.
