The New, Newer Project: Part Tres...

Not really. I didn't hear any sloshing sounds afterwards.

The cleaning continues. I have been carefully wiping down the underside of the car with some rags and a little diesel fuel. The diesel method seems to work wonders on the original exhaust system. It cleans the surface rust right up and then slowly evaporates leaving a slightly less rusty looking exhaust system. [img]<<GRAEMLIN_URL>>/grin.gif[/img]

I found some interesting items on the rear differential after wiping the grease off. It looks like the differental was half-heartedly blacked out on random surfaces of the tubes and the center section before installation at the assembly line.

Here is the factory GYC stamp code (3.08 posi) on the partially black painted axle tube. There is also a &quot;191&quot; stamp which could be the date of assembly (191st day = July 10, 1973) which matches with the late July build date of the car.



and here is something I haven't seen before: a yellow ink stamp of the same &quot;191&quot; on the upper webbing of the center section.



An orange &quot;G&quot; on the top and bottom of the center section:





Some green paint marks on the upper portion of the axle tube, partially covered by the black paint:

And the underside view of the axle tubes, one side with black paint and the other, not so much. (and the shinier-looking exhaust after I wiped off the surface rust.)

Cleaning continues. I used some dishwashing soap and water in a bucket and sloshed it all around the wheelwels with a soft carwash brush. Got most of the road dust off. I then used the diesel-damp rag to wipe everything down including the frame rails. It seems like the assembly line used a bit more black-out paint on the passenger side than the driver's side. Looks like they were just trying to cover the white frame rails and a bit of the wheelwells. By the amount of non-coverage on areas shaded by things like the lower lip of the inner wheelhouse and the sway bar bracket, you can deduce that they didn't move the paint gun around much and just blasted it from one position.

I also pulled the brake drums and gave them a quick dip in the evaporust which removed the surface rust immediately (once it was warmed up to 70 degrees in the sun). They look asssembly line fresh now.

[njsteve]

BTW, what I previously thought was a small section of black paint on the flange area was actually the portion of the drum that mated up to the wheel, and as a result never surface rusted.

What a car Steve. I always enjoy your threads!

Thank you! I always enjoyed the archeological aspects of the hobby: unearthing things that haven't been seen in eons. This one is fun because there is a lot of hidden markings and manufacturing idiosynchracies that I have noticed while laying on the mechanic's creeper underneath this old bird. More photos to come when I get towrd the front of the car!
