Rough cut and filed both brackets to finish size. Need to get a Scotchbright wheel so I can debur and polish the brackets. Next step is to drill the 9 #30 holes in each attachment bracket.
,,,after further scrutiny, I didn't cut the angle on the side of the brackets correctly (see image 3). First Oops! Oh well, I need to take some paperwork down to Van's anyway and will pick up some new angle and try it one more time.
