DIAGONAL BRACE SET-RADiator SUPPORT - The 1947 - Present Chevrolet & GMC Truck Message Board Network

GeorgeLeonard · 09-02-2011, 08:38 PM

I worked on my front clip today and found that both diagonal braces were broken. I didnt even know it until I started taking things apart. My question is: Are these things even necessary? There must have been some stress on them because they were broken. How do you get behind the rivets- by taking the radiator out, I suppose? Can I use other holes? Is there another way to fix it? Can I leave the braces off and not worry about it? They are kind of flimsy looking but Im guessing that they wouldnt be there if they werent needed. Right?

If they were not necessary GM would have not used them.....yes they are needed to keep core support square

Okaaaay.....so what happens if my core support is not kept square? As I said in my post, I didnt even know they were broken until I started taking things apart. I bet a lot of people are driving around with broken braces without knowing it.

They removed them for A/C condenser installation originally. I guess the condenser stabilized the rad support.

I guess i should replace mine then, huh? They were were cut when i got the truck. I just tore out the pieces a couple weeks ago. (all the while thinking "Man, this really cleans things up in here!" Haha...

Mine have never been on my truck since I bought it and I have never even thought about it. It was only recently that I even realized they were supposed to be there so I wouldn't worry about it.

My 65 has factory air and the cross brace was still attached....

I've not had those braces on any of my trucks over the years, and have not had any issues as a result. I think they might be a good idea if the truck was being used hard, as these trucks were originally intended to be used. More so on a 4x4.

if they are missing the stress is taken by the radiator to keep it square, not a good alternative!

my radiator is mounted in rubber to the frame , and I am installing AC so if they are in the way , they won't be soon...........

I wonder what caused them to break?

and everything else on that frt end pretty well mounts or attaches to that rad support, which most attach to the main body. s
