Well, now that you say that and I think about it more, I'm no longer certain. It's been several years now since I've had any of mine out of the car. Maybe it wasn't felt. Could have been foam.So in short, please don't anyone take what I said above as being the gospel truth - I might be wrong.

Nice work, and great write-up! I edited the thread title to make the topic more obvious, merged the two threads and promoted it to "Tech Article".

I think the factory used felt, there were remains of it on most of my panels. (Well crushed, of course.) I've tried replacement felt, but I don't think the self-adhesive felt you can buy these days is thick enough to cushion it. The closed-cell foam is a better solution.

Are the feed hoses from the float bowls to the jets kinked? Looks like it in the pictures.

I'm not sure I understand what part you are trying to remove. Pictures might help. You are aware that the spindle is an integral part of the strut?

I like it, Rob. Clean, classic and functional. I'm not feeling the Kosei's too much either, but they aren't bad enough to spoil the effect. Great work!

That's the same balance tube and configuration as on my very late '71, Dan. Yes, both of my master-vac hoses have badly aged cloth tapes on them. No way they're going to come off intact. No idea what to use to replicate that. I suspect that they used to be labels back in the day, similar to the ones Dan pictured.

I so want to put one of those V-12s in a Z....

So any thoughts on what type of tape will be appropriate for this purpose?

OK, we can eliminate the engine and the transmission input shaft from the discussion. That leaves the rest of the tranny to worry about.

Does it vibrate when revving in neutral? Test with both clutch depressed and not.

Then the rear end and u-joints are not the cause. If it is always RPM-linked, regardless of gear (or road speed) it has to be in the transmission or engine.

Does it always happen at 3000+ regardless of gear? Or is it only at 3000+ in top gear?

Randy, I thought that white ring was a piece of cloth tape - I guess I'll need to look at mine a bit closer. Can't tell for certain from this close-up, and don't have the car with me today.

Jeff, I can merge the two user accounts under one of the two names. Send me a PM.

I have those as an upgrade in my '71. They are from a '72 or '73 240Z. Don't know whether they were used on 260Z or early 280Z as well.

Excellent! I'll be wanting a set. But probably not until next month, as I already blew through my car budget for May!

Yes. Runs behind the engine to feed coolant to the manifold plumbing.

I've seen pictures of that wheel before. Can't recall what other Datsun model it came from.

But are they reinforced as well as fuel/oil resistant? Or will they collapse under vacuum?

Jay, are these the correct reinforced type hose?

Some are, but some aren't. There are even a few that are mixed with both Series 1 & 2 parts. You'd need to look at it closely to decide.

The reason you have seen both ways is because 240Zs were built both ways. The large reservoir is always for the front brakes. The front calipers require more fluid than the rear cylinders do. The '70-71 240Z had the large reservoir at the front of the cylinder (farthest away from the firewall). The later '72-and-up cars had the large reservoir nearest the master-vac booster. I don't know if the prop valves are different or not. I know that to use the later master cylinder on an early car you have to reverse the lines to the prop valve. But which line goes where on a '73? I don't know for certain.

I'd be afraid that the red filter might clash with the blue engine block.

I prefer the blue factory look, and it doesn't really cost any more. My dealer keeps them on the shelf, they're about $6.50 each after club discount. Some of those listed here are rather ugly IMO, especially the Fram. That one is way too ugly to be on my car.
