Thank You Rick, Is/Was the adjustment mechanism (at the bottom) Natural Finish Steel ??? as Ive seen many builders with zinc plated (yellow and clear)
Do you have any COSMOLINE spray on your Natural Steel Pieces What is that backing plate painted with...looks very much like natural steel ??? I need to see/learn where E-brake cable connects....Maybe it will be obvious once I start assembling all the above...........
