Unidentified radiator fitting
Im getting close to getting my truck running I've got the transmission lines instlaled and put the radiator in tonight. It has this extra fitting on it and I think its for an ac truck but I'm not sure. Should I just plug it? If so, brass plug, or will that mess with the copper in the radiator?
Thanks!

Re: Unidentified radiator fitting
looks like heater hose return fitting, not normal for 67-72's, and yes plug with PTFE tape wont hurt

Re: Unidentified radiator fitting
If it is an automatic with a V-8 I would use it. Here is a diagram showing the heater hose configurations for our trucks.
