wow was just going to the garage to make more fender brackets and hope to have one on today. what a hassle or locating them in 3D and matching too.
had to cut off 1 1/2" off the back and split another to add width(weld two together)
THEN a motorcycle guy said I coulda got the right width motorcycle fender (probably 12x the $$$$$ tho)
if u still wanna go to NorthernTool.com like #25 each, few different sizes. maybe just order one to check it first

asked for advise here about a month ago an some dude drew me something for bracket, but that was for drum brake attach. he wasn't kidding about ~1 1/4X 1/4" thick bracket though.
I reinforce the ~ 1/8" fender with 1/8" strap, use excess to approximate where my actual bracket will bolt to. then try 3/16 thick flat piece with two bolts holding (read : washers for spacing). then ANOTHER bracket from the upper ball joint big bolt. damn what a hassle 6 pieces per wheel but the only way i could figure it out to offset the brackets and space them properly and semi/cleanly.
HAd to do this cause my fenders were close width, not allowing for the curve of the tire clearing the bracket, so bolt/spacer washers.

but, you gotts do what u gotta do.
