Help: Need source for engine mounting bushings

[52crankman]

Anyone have a source for the OEM engine mounting bushings (11345-N3000) that are pressed into the rear manual transmission mount.

crankman, you just need to put those part numbers in to an internet search engine and see what you find.  I think that people have had success with Nissanpartsdeal.

All ready tried them with not luck.  No luck with searching the web either.

Tell people what you've done and you'll get there faster.  We don't know where you've been.

You might consider just buying a crossmember with the mounts still in it.  Probably cheaper than new mounts.  They don't see a lot of abuse, unlike suspension bushings.

What is your objective? To get new bushing because yours are worn out, or are you restoring and want new bushings?

I can get you a decent crossmember with good bushings if you are just want to improve things. It's just as important to get a new trans isolater mount as well if you haven't done so yet to get your drive line angles back to spec. I couldn't believe how much my old one had sagged when I was chasing a drive line vibration. Nearly 1/2 or 3/4 of an inch!

I am restoring this car and want to replace the bushings.  Interesting all other bushings are still available but have not yet found a source for these.  They seem to still be in good condition but would rather replace them after all these years.

Here's some poly replacements from zcardepot.com if you can't get OEM.

Here is a test you can do to determine if your current bushings are "ok" or need replacing.

Clamp the cross member in a vise or to your work bench VERY solidly.  Put as large a screw driver as you have through the hole in either bushing, or similar stiff rod, at least 12 in longer, longer is better.  Put the tip of the bar in the hole, and leave as much handle length as you can out.  Pry like mad on that bushing and make it flex. Inspect the stretched side for cracks in the rubber or separation from the center tube or outer shell. Do this in several directions. You might be amazed at the cracks you can't see with the bushing in its neutral position. 

I'm not a fan of the poly bushing in the trans mount. Noise transmission will be worse. Unfortunately if you remove the stock bushings and the outer shell to put the poly bushings in, then don't like the resulting noise, you can't go back to the stock bushings....

That said the series 1 cars had one cross member style that did not have bushings at all at the crossmember/body connection point (got it on my 71 right now) and I don't hear nothing from the trans...

If I get a chance I'll drop by my local Nissan dealer and see if Canadian Nissan has access to those stock bushings too.

I think that he's just decided to he wants to put new rubber in.  Not unreasonable, if the bushings were readily available we'd be saying "why not?". I imagine that they can't be found because Nissan had a very low inventory of them, because they're almost never ever replaced.
