Harrison radiator ID tags

[cbeerman]

I did some searching and didn't find much information about these tags or the applications on our trucks. I was wondering if this might be something that others are interested in, hopefully members will post their tags and provide whatever information they can.

These Harrison tags have the radiator's tank id and core size on the left. The broadcast code of the radiator is on the right and along the bottom on the part that sits on the core there should be a stamped GM part number.


This is what I believe to be the original tag from my 1968 GMC K1500 305E SM465. I also think the truck has the RPO V01 HD Radiator option.
My tag is rusty and I am unable to read the GM part number along the bottom.


Lets see what you guys have out there before they are all lost to time.

I looked into this a bit ago and I agree, there is not a whole lot of information related to our trucks. If several owners of original tags would share their tags, we could piece quite a bit together.

My truck was built January, 72. Many of my parts were manufactured December 71 and my radiator fits into this and a date stamping of M1 (12-71). Pass tank "AT", driver's tank "IA".

My configuration is 350, th350.
