The New, Newer Project: Part Tres...

Thank you for the compliment. Just trying to have fun. [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]

I took the white car over to my buddy's garage today to get some underside shots. I took around 140 photos of just about everything. Lots of neat stuff under there that I have never seen before on a second gen car. The camera didn't have a wide enough angle lens so I had to shoot the car down the center, then down the sides to get all the details. So here goes:

The right side. Note how little paint got on the lower portion of the rocker panels on the passenger side. The driver's side rocker bottom got a lot better coverage. Must have been a shorter painter on the left side of the paint booth that day.

And the driver's side:

Here's something interesting. I have never seen this bracket on the cross member the purpose of which is to retain the speedometer cable.



This clip is on the driver's side inner frame rail:



This bracket is on the driver's side inner frame rail below the steering column:

French locks on the exhaust manifold bolt:



Matching VIN on Turbo 400 transmission:



Unpainted, galvanized floor plug



Emergency brake adjuster with single, nylock lock not.



GM stenciled fuel lines on subframe with color coded spring clamps:





Fuel pump part number:



&quot;FU&quot; paper tag on front sway bar:



Driveshaft color coded paint stripes:



Limited Slip metal tag in factory installed position at bottom:



Orange painted &quot;G&quot; on the bottom of the differential. The differential center section appears to be natural cast iron, with the tubes and mounting plates painted black.



&quot;LS2&quot; on the underside of the radiator support, denoting the SD455 option:



Yellow crayon &quot;53 H&quot; on the inside of the passenger side subframe rail:



Original spiral shocks all around. The car rides very nicely on them. You can see the black painted rear differential base plates:

And here's a comical one: Nice build quality/alignment on the rocker panel installation. [img]<<GRAEMLIN_URL>>/rolleyes.gif[/img] It is sticking out about a 1/4&quot; from the bottom of the quarter panel. The passenger side is flush with the quarter.

Has the exhaust system been replaced?

[njsteve]

No, that is the original exhaust system, including muffler. The SD455s had a unique system made of multiple tubes that were welded together to make the long sections.

Started tinkering yesterday. The original master cylinder was leaking badly at the rear seal by the booster. Brake fluid was running down onto the subframe. Luckily I still had the reproduction master cylinder left over from the black 72. So I installed that one as a stuntman for the original one while I send this one out to Whitepost.

From sitting for 40 years with the same brake fluid, the bottom of the reservoir was filled to about 1/4 inch with rusty colored goo. It was a bear to get the inner far piston out. That same rusty goo was in the bore area as well and not only pitted the bore but devoured the valve itself:

You can see that these master cylinders were painted a flat black originally. Not a lot of the paint remains but it is there in places.









Here is the reproduction bleeder style master cylinder in place with the original cap and bail on it.
