70 rear valance, bumper bracket, and bumper flat washer finish

[Bill L.]

The two inside bolts for the rear valance to body have flat washers and bolts separately. Are the flat washers just plain steel, bright zinc, or zinc phosphate?

Are all the SAE flat washers used for the bumper mounting brackets and bumper to body plain steel along with the lock washers? Archives seem to indicate zinc phosphate while lock washers were plain steel. Just trying to reconfirm.

On a side note it has been discussed that the bumper bolts are generally bright zinc on the out side and zinc phosphate on the unseen side. Mine all appear to be zinc phosphate. I see no evidence that any were bright zinc and all the hardware is in pretty decent shape. I have seen bright zinc remnants in other areas. For example the clips that hold the fuel line to the frame back by the gas tank still have a little plating on them.

Thanks as always.

1. Rear valance panel washers I assume you are referring to the bolts above the exhaust bezel most common natural steel.

2. Rear bumper to body bolts washers most typical silver finish but have seen natural. On the brackets washers tend to be on 1970 till some time in 1971 natural, silver and black in that order.

3. You are correct in that the original silver finish seen has a less bright look but then what is seen on original car has dulled over time and would been some what brighter when new.

Thanks Paul

That is a big help. All the bolts appear to have been the same finish as the hood latches.
