it would be easier to buy a 8 piece notch, but with nice tools you have access to, it would be much cheaper to build one. don't use anything thinner than 3/16" thick. you can buy 12" wide sheets of flatstock to cut your notches out of. that shouldn't be too expensive. make sure that you will clear your axle and any brackets__ with the inside part of your notch, at the top it's generally the narrowest/smallest part ( //-\\ ) i'd try to match the size of the notch with the size of the frame, you know what i mean, say the frame is 4" tall try to make the notch look like factory, for aesthetics. i like things to flow, so maybe that's just my preference.
i've ran into problems with the frame buckling when my bags were mounted on the lower link bars, so when i redid my rear setup last week, i plated the inside and top of the stock frame with more 3/16 flatstock. my frame was dented in the top and bulged out in the inside. guess you can say i learned the hard way? moral of the story: reenforce your frame where your going to mount your bags. there's no such thing as overkill. also its a good idea to run gussets on the inside of your frame/notch wherever you are going to have a transition between angles, drill and plugweld them. its just smart.
if that was confusing in any way, just ask and someone can probably explain it again in a different, less rambling way. i'm terrible if i can't draw pictures or use my hands
BTW that was supposed to be a pic of a notch up there in ( )
