I wish I enjoyed cleaning as much as you. I've got everything out of my car right now, but I hate cleaning.

Pull the two ground straps, fuel line, add the tilter and it's ready for plucking. Just added 250 new songs to my music list for the shop. Time to get busy!!!

Graeme,

What are the dates on your exhaust manifolds? Thanxs Dave

NorCam · #**194** 12-31-2019, 02:42 AM

Tough to read the driver side Dave, but the #3942527 looks like it's dated A 30 9 if I am seeing it right. It is pretty tough to discern the rough date casting on the drivers' side. The passenger #3946826 is a little cleaner and looks like E 9 9 but that may, in fact, be F if that date makes sense?

I was thinking of having my buddy tumble these in his shop. He did an intake on my 68 a couple of years ago and it came out looking great with a factory perfect finish. Has anyone here ever tumbled a set of cast manifolds?

I think Jerry M tumbles them during his restoration process, but that's a huge shipping bill for me to send them from here so I might see how these do at my buddy's shop.

Good work NorCam.

I decided to stay focused on the rear half of the car and dropped the fuel tank and the rear diff out to get better access to cleaning the floors. Once the floors and the springs are cleaned up, the diff will get the same treatment and all the hard lines will be semi-restored before going back onto the frame rails and diff housing. When I dropped the fuel tank, I saw these numbers "47" written in red if that means anything?

With the differential pulled and set aside for clean up, I started looking at the springs and saw this crack on the lower spring on the drivers side. I pulled both pieces and will have to get a new one made to replace it. I now have really good access to everything out back and will get all this cleaned up over the next week or two before it starts going back together.

I think the 47 is a sequence number used on he assembly line. Mine had a "3" in a similar location. I'm curious if you have a mill stencil on your tank similar to mine. I had to do quite a bit of cleaning to get to it.

Graeme

Nice work.

Mike
