Advice on ‘74 Duster

The body of this car looks OK, but I would be cautious, the duct taped overflow tank, the location that the mounted the MSD box, and no battery hold down along with hard to say but smallish looking rad. Its not these things in particular its more that there appear to be cobbled and if the cobbled on these things then where else did the halve *** stuff, I would definitely go over this car close before buying. I learned that lesson from this site on a 69 Cuda I was thinking about.

I went and got a battery hold kit at pep boys, your standard J hook set up with a rubber brace that goes across the top...my problem is there isn’t anyway to hook the j hook to the bottom of the battery tray as it’s flush with the fenderwell. No way to hook it to anything! Any suggestions? I thought about drilling a hole through the tray so I could at least have somewhere to hook thank hook to, what do you think?
