I have decided that to save a lot of time and messing around that the mounting posts would only be available with the EZ bracket provisions AND the brackets will be Stainless Steel.
With the 316 Stainless steel, it can be polished to a mirror finish or can be painted.
I will meet with the machine shop tomorrow to finalise cost. Also the kits will NOT come with bolts as the bolts bump the cost up for postage (International guys would pay +$20 for $5 worth of bolts)
