Here is an Aluminum bracket. Kind of a cross between Z and L shaped. It's app 6" long end to end, 4-3/4" wide side to side and .256" thick. There are six 8-32 thread thru holes, two 6-32 thread thru holes and six thru holes, just under 3/16" diameter. Weighs app one half pound. Assume it's 6061 Aluminum. I'm calling this used, only because it's custom made and machined. A few minor blemsihes from storage. No vendor info or packaging. Free shipping via USPS package / box with tracking. I have a few available. If you have any questions, please let me know. Thanks.
