The good thing is that anyone who even spends 30 seconds to Google the VIN will find this thread as second on the list.  As far as I'm concerned, anybody bidding on this car gets what they deserve.

I'm no expert by any means, but the 6's look much different.  The "known correct" one that sides of the sixes are arc.  The one the OP was questioning the sides of the sixes have an arc.  This to me looks suspicious.  Slab side sixes are not usual for easily purchased stamps.

I know many industrial fasteners are black oxided, which is a multi-step process and as such more costly than manganese (dark) or zinc phosphating.  My understanding is that due to cost savings GM went with phosphating most fasteners-brackets.  There are some exceptions.

I think the flakes might be "SALTS" precipitation, Filter them out with a coffee filter- one possible "solution" (Pun intended!)
I need to purchase some Ph testing strips to keep tabs on my concentration levels and "sweeten" the solution periodically to maintain effectiveness.

Jackpot!  I think you are correct.

Good idea on the Ph.  I wonder what a good "range" would be?

I know he mentioned that using HARD water instead of distilled water can cause surface finish streaking, & maintaining your ph range is critical to the solutions effectiveness.

I've only been using distilled water.

On a somewhat related topic, were there any internal changes to the 302 when they changed from the 6-8 to 6.5-8 tach?  I'm thinking screw in studs and guideplates?  Did the 302 ever have screw in studs and guideplates?  I seem to read differing statements on this.

My used solution get whites "flakes" that tend float around in it.  It still seems to work OK.  Any idea what these are?

Hood hinges and latch catch are manganese phosphate. Bigger darker almost black crystals, must be oiled and is used for applications where parts rub one another.

The black Zinc on bolts is a passivation conversion from silver zinc using a chemical dip.
Same with Yellow, Clear, and Olive. ALL four are Passivation conversions of silver zinc which modify the surface of the ZINC coating into a harder surface more resistant to abrasion and corrosion.

FWIW I have been ZINC plating parts lately and as a sample I have had a fender shim laying in the driveway since January and it has yet to show a spec of rust yet.

First I've heard about the hinges and release mechanism being manganese phosphated.  When I stripped the paint from my originals, they were a lighter grey more like zinc phosphate.  When i zinc'd mine they came out a dead ringer for the original grey.

Are you guys using it mostly on bolts? or what other items are you using it on?
What is the process for using it on bolts that is the most simple?
The big parts on our cars are the hood hinges-springs and the hood release mechanism in front of the rad support.

Other non-fastener items CAN be the Hurst shifter mount plate, the Hurst shifter housing (check first, it varies on when made), shifter-backdrive linkage.

Stuff works great.

Got some white "floaties" in my premixed-reused solution.  Doesn't seem to affect anything as far as performance.  Any concerns?

Hey Bullitt!

No!!! I hate clear it stays in a garage and likes the paint job NATURE gave it! Plus when I take it out everybody asks when RU going to restore or paint it! I would get bored if I didn't have to answer all the same questions! Tks! Bill

It was interesting to me that the 'dykes' rings were not mentioned... (for drag racing purposes)...

Very popular on 2 strokes in the 70's.  Single rings located very close to the top of the piston.
