I went through the same thing a couple of years ago. I finally sent a box of parts off for plating. I seem to recall it was about $50 for about 7 pounds of parts- that was a lot of parts. I sent off things as small as the triangular wire tabs that go on the jack straps. Also hose clamps, gas tank clamp, strap that holds the charcoal canister, clips that hold the control cables to the defrost boxes up front, etc. Lots of stuff that was not originally yellow zinc, but it dresses things up nicely.
FYI- below are pictures of door latches- Left to right top row- used, OEM/NOS, plated dull yellow zinc, and plated bright yellow zinc. Bottom row- OEM/NOS, OEM/NOS (I robbed the bumper to put on my car), dull zinc and bright zinc.
One or two of the OEM/NOS almost look like clear zinc, but if you rotate them around in the light you can see a yellowish cast.
Note the different vintages of latch. They really fine tuned this part of the car over the years!
