Someone asked me about making the chf plates for them. I called my buddy who does the welding, drilling, and grinding and he doesnt want the liability. Sorry guys. Im attaching a diagram that might help you if you want to get them made. The diagram is for a 5" inch total plate. The guy that posted the diagram had already increased the arms of his frame rods so the plates shown are smaller. Two 4" inch plates welded together with a 1" inch over lap works well.
It time consuming but mounting the bottom plates first then marking the holes for stock, chf on the top works best.
I used 12mmX65mm flanged bolts and flanged nuts to secure the bottom of tge bracket. The top used the stock bolt from Ford. Top bolt torqued to 66 lbs and bottoms to 70 lbs blue loctite on all bolts.
If you have questions let me know.
