I might be wrong but aren't there two different types of curved ones? I've seen some that look bent in the middle not just one long bend.

I just mounted the curved ones from a GP to my Monte SS. I have the hole in the core support and I clipped it just like you mentioned above but there are zero access holes in the inner fender for me to bolt to so I drilled holes and used body mount bolts right into the sheetmetal until I find a reason to cut a hole in my inner fender and use a proper nut and bolt to secure it on that end.

What he said. Drilling holes was involved but there was room to reach behind with a nut.

I was under the assumption my car called for the straight bars since it's a '78. After closer inspection there aren't any provisions to mount either. This doesn't necessarily rule out using either bar so I'm going to post the differences if anyone is planning to use either set. If you're running either set, please post what car you're using them in and whether they're straight or curved to clear up some confusion. Most of this might be self explanatory for a lot of us, but hopefully it will be of use to someone not as familiar with g-bodies. Feel free to add corrections.

The curved bars measure about 29.5" long
The straight measure about 26.5 long

Here's the inner fender on my '78 GP. Notice how there aren't any holes drilled to mount anything.

Here's a mock up of where the straight bar meets the fender. I'm holding it in place so it's higher on the fender than it would be mounted. Notice where the round hole to the lower left is located.

Here's a mock up of the where the curved bar meets the fender. I'm holding it in place so it's higher on the fender than it would be mounted. Notice that the round hole is directly underneath the bar now. This tells me the curved bar is the one I want to use.

Looking at the core support end of the bar, you'll see that it's flat on one end, recessed on the other. The flat end installs on the core support. If you have it upside down on the wrong side it won't fit properly.

This is the hole in the core support that the bar attaches to.

Here's the clip and bolt you would use to mount them. You can always improvise with something from a hardware store too if need be.

These are the two different style clips to mount the braces. The short ones are for the core support, the longer style is for the fenders. If you try to use the short style in the fender you're going to be disappointed. If you prefer, new hardware will work as well and look much better anyway.

Here's a pic of the long clip slid onto the fender from the access hole. Note that if you're removing these from a car in the junkyard be careful. If they fall into the fender kiss them goodbye.

Here's the curved bar mounted to the core and mocked in place with the clip. Ever wonder why the overflow tank was shaped that way? Now you know why.

From here I would use an automatic center punch to mark my drill point and use the appropriate bit. It's a done deal from there.

So what are you going to do with those straight ones you got there?

Someone else mentioned interest in them but if he doesn't want them you have dibs if you want.

OK let me know I am hoping to get a set here soon.

If I don't hear anything by tomorrow when I get back in town, they're all yours. I was asking $30 shipped. All rust has been removed and they've gotten a few coats of black paint. I planned on using them on my car so I wanted them to be pretty :lol:
