Not that its a huge amount of info to go on, but I got some NOS hose clamps which are correct fitment for the 520 truck heater, in their bag, and they are clear/plain zinc.

I'm working on a different era of hose clamps, period mid 1960's for the CSP311, and it seems Nissan was in the midst of changing and constantly changing, thread, head and style of clamp, and for different places on the car. I think its also a moveable thing through the S30 pruduction years.
