To finish up on the gas tank to filler neck hose; as I mentioned previously, Chick had suggested soaking the rubber in baby shampoo. So I sealed it up in a ziplock baggie coated with the shampoo. The outer ends seemed to feel more flexible after soaking for 24hrs. Center section that was exposed to fuel fumes didn't seem to change but still worth trying and I believe it is worth it on rubber components just be advised test the procedure on a scrap piece before hand.

Next I tied up some loose ends and finished the exhaust bracket hardware, T-bolts & nuts, rear brake hose bracket (note only one bolt used from factory)

For whatever reason I keep getting errors when trying to load more photos. I'll try again later on.


It may not look like it but I am more satisfied with the quarter wells.

Image issues seem to be resolved.

Got a similar project going and trying to do a preservation on a 1968 z/28 matador red with what I believe to be original running gear. Really appreciate your post
I might explain the driveline shudder....the bottom half of a balanced driveshaft has 20lbs of dried rubber stuck to it.o_O:unsure:

Photos 889 -891 - Drivers spring installed. Ignore the finger prints from the gloves. You will also note off to the side you will see I also installed new (actually used but still flexable vs the originals had dry-rotted) rocker "drain flappers" (technical term)

These photos are of the initial teardown. As you can see the 40 plus year old gear oil had failed. Current plan is to reuse the carrier which I believe might be the original to the car (can not verify) but since the speedo cable was apparently routed the non muncie way I can route the cable (which I still have CA) and assuming the car had a speedo adapter it would reach and have no issues. You can also see a wear pattern where the cable rubbed the firewall.

One thing I failed to mention previously was that I will be swapping gear ratios to a 4.56 as I plan to run a 28" tire and I will need this little small block in the rpms fairly quick or at least that is the intent. Of course new bearings, seals, brakes and an overall clean up will be the following steps to come.

Up next was the removal of the pinion nut & pinion as well as removing the carrier & axle bearings and said seals. Also adding the axle stamping & casting date.

Photos 908 - 910 - Old axle bearings removed and new bearings and seals installed. Also added a shot of the inside of the tubes. Very clean once the grease was removed.

Last for today was the removal of the pinion races (Not pictured) and the "new" gear set. GM dated 10/65 & 11/65 ring & pinion. Hopefully up next will be the "derustification" of the housing and the installation of the carrier bearings and start to setup the pinion depth etc. Once that is finished I will set up the backlash and get a wear pattern.

10/65 and 11/65? I see the dates but those gears aren't original to your car.
