Originaly posted in the garage but no responses. Need opinions on whether 5/16" plate would be strong enough for disk brake mount flanges on the end of the axle. I'm using 2003 HD disk brakes and E-brake setup but the problem is I have to extend the backing plate flange on a 14b axle by 5/16 of an inch to mount the caliper brackets in the right place. I've cut the mount flanges off of the 2003 axle and they are 7/16" plate I'm thinking of having these machined down to 5/16" and then welding them onto the existing axle flanges in the position I need them. Anyone have any experience with this?
