Making the Bracket
I used 3/8 plate for the bracket. I used 8mm hardware and drilled the holes using a 21/64 (8.33mm) bit. You could use a 11/32 (8.73mm) bit if you didnt have bits in the 64ths range.
Fairly simple, cut a 4-1/4 by 1-3/4 rectangle. I wait to cut the angles until after I have drilled the bottom two holes because a square plate is much easier to secure in a drill press.
Centerline for the holes is 5/16 of an inch up from the bottom. The first hole is 3/8 from the left side of bracket. The second bottom hole is 2-3/8 center to center from the first hole, again up 5/16 from the bottom. (test fit)
On the top of the bracket measure 1-1/4 back from the left side and mark it. On the right side, measure up 1-1/4 up from the bottom and mark it. Connect the marks and that is the right angle. Cut it off.
For the left angle, insert your bolt and washer in the bracket hole and draw a line from the upper mark you made previously to the edge of your washer (plus a little if you want). Cut it off.
BEFORE you drill your upper holes you want to mount the bracket in place with the bar mount tabs OUTSIDE the brackets to mark your drilling locations. Use the R-Gaza supplied bolts and spacers and mount the bracket in place.
Looking down from the top, position the R-Gaza bar mount tab so it will clear the rear bolt spacer when you move it to the back of the bracket during final installation. Take a pencil and mark your bracket using the inside of the mounting tab holes from the R-Gaza bars. The R-Gaza mounting tab holes are elongated to allow for adjustment.
Pull your bracket off, drill the upper holes for re-attaching the R-Gaza bars in the middle of the slotted adjustment markings.
Test fit and identify any welds or obstructions that would need to be clearanced before you paint the bracket. Remember that the R-Gaza bar mount will go BEHIND the bracket in the final installation. A little grind and wire brush to round the edges and you can paint.
Mounting is easier if you loosely install the bracket on the R-Gaza mounting tabs first. The bracket goes IN FRONT of the R-Gaza mounting tabs. Then attach the long bolts with some Loctite and the spacer. Once both lower bolts are tight you can Loctite and tighten the upper bolts.
