Good quality part fit perfect

Slightly narrower fins than the original. Overall width, length, and height are the same though. Tubes are about 1/4 inch shorter than the original, but not enough to cause problems. Only time will tell. Original lasted 53 years. If this one lasts as long, I won't be around to know it.

Good heater core still works great in my 1978 ford truck.

Seems good and it technically does fit, it’s a little smaller than factory so be prepared to use some styrofoam to pad it up a bit. Otherwise seems to be working fine. 1975 f250

Worked like it should on my 71 F100. Just like a couple of people said though the hoses coming out are a bit shorter.

Does not fit as stated. I made it work by setting it on a 3 inch x 6 inch foam pad. And also added stripfoam on the top.

Product was as described and fit well, nice to have heat again without any leaks. Product arrived before expected date, would buy again.

Finally got around to installing this. The only thing I didn't like was that the inlet/outlet pipes are shorter than my original. Truck is a 1966 F600. It came with foam to seal the gaps which was nice.

Fits good in 73-79. A bit smaller than original, but still fits great.
