4-Row Radiator Swap Question
I'm going to upgrade to a 4-row radiator in my 71. Since this is my daily driver I don't want to take it apart and then find I have to go looking for more parts.
I have the upper brackets and rubber; my question is what do I need to do at the bottom - do I need new brackets there as well? Thanks! Richard

Re: 4-Row Radiator Swap Question
Yes, there are upper and lower brackets. If you have a smaller rad, you will have to drill out the rivets on the old bottom brackets. You will need new nuts and bolts to bolt in the new bottom brackets. You will also have to get a pair of pliers and carefully bend the bottom lip of the core support in order for the new bottom brackets to fit. I can get pics for you, but if you have the assembly manual for our trucks, it is shown in there.

Re: 4-Row Radiator Swap Question
You will need the top and bottom retainers. The bottom retainers were rivoted to the core support for trucks that had a 4 core rad originally. Some Chevy vans i.e. (73-80 something) c20 -30 w/air and a 4 core rad have the same retainers.

Re: 4-Row Radiator Swap Question
Richard, Crazyray, glad to help.
Here's a little something else I noticed about the vans and was wondering if anyone knew for sure. The 73-80 C-30 Dana full floating rear w/ posi will this work under the 67-72s? Looks like the rear is almost the same width. Thoughts... |

Dave, that is a good trinket. I have a van chassis motor home (class c) with that floater rear end.
