Dented k frame

If everything measures square it’s probably ok from a structural standpoint. Check the welds for cracks, but that goes for non-damaged K members too. If you can get decent alignment numbers, it should be fine. Obviously if you can’t get a good alignment then it’s time to replace it.

But even if you find the adjustment is all the way maxed out on one side and not the other to make the alignment work then it could be like Jim said and something is a little moved. If that was the case then I’d be looking for a new one.

Just replacing it isn’t necessarily a guarantee either though because there are lots of these 50+ year old parts that aren’t straight anymore. I’d rather run a K that’s dented and ugly that I know measures straight than buy something off the internet that looks good but might not be.
