Knowing that these gussets rust out from the inside. AS we can clearly see on the inside bottom of one of them where there is rust pitting.
This is due to that these gussets can not perfectly fit the body and NOT allow water to get in between these gussets and the body and thus allow rust to develop.
So...when a person goes to install these it is wise to use a non-hardening flexible seam sealer and pump it into the bottom of this gusset so it fills up the cavity at the bottom of this gussets and reduce the chance of water being able to lay in the bottom of this gusset and allow rust to begin.
I myself use one of two products. One is CR LAURENCE 7708...and the other is SEM catalyzed beige seam sealer.
Just because the SEM product is catalyzed does not mean it gets rock hard and will chip away over time.
The CRL 7708 will remain flexible all the times and is really gooey.
The reason I may use one over the other is all depending IF I am applying the SEM beige seam sealer on other areas of the car that the CRL 7708 cannot be used because I need for the sealer to remain flexible but yet be solid enough to allow it to be painted on. So while I have the cartridge out with the SEM sealer....I will use it on the gussets if I plan out my work schedule accordingly or that.
regardless of what is used, make sure the body of the car where the sealer is going to make contact is CLEAN. Applying a sealant on dust. dirt or an oily surface is pointless.
Regarding those ill fitting radiator support brackets which are great for stock radiators but not so much for aftermarket aluminum ones (at least the one I bought) these just don't make good contact and would gnaw through the rubber in a few hundred miles. I gotta try and make my own.
JR73, I can look at mine when I get home on Thursday how mine is sitting. I do not remember it being a concern when I put it together but you have me wondering now..

It's just something that would bug the heck out of me.
Besides it should be a fairly easy job.
Another rust issue I need to take care of before I set the body back down is the #3 mount rocker channel area.
Most of that hole is rotted away. The insert I got from Bairs Corvette will cure that and make it solid again.
Had a chance to do some machining on my billet aluminum radiator mounts.
The factory mounts don't really fit these square aftermarket aluminum radiators very well so I'm trying to improve that.
Nice machine work! Are you still planning on have a layer of rubber to insulate the new mount to the radiator where they both make contact??? Such as where the tank is welded to the core.

exactly Dub,
aluminum is soft and with the vibration it wouldn't be long and something is gonna start to wear so yes I will get some rubber in there.
Have been doing some machining on the other aluminum rad mount when I get time (things are complicated at work lately)
Prepped my shop for indoor sandblasting, Hung as much plastic as I could to contain the mess.Tried to blast the rocker channel area so I can weld the insert in. The whole shop had a haze in it that I could smell when I took off my respirator mask so I quit for the night cuz that stuff aint good to breath.
.Got that area cleaned up enough to weld on, now for some weld thru primer.
