Hi all, now that I have modified my 73 240 to over 200bhp, I feel that under heavy acceleration the rear diff is moving around. I think there is a uprated mounting available for this can anyone help?

Any info would be great..Thanks..

You could use the solid front diff mount. It probably won't be any noisier than having the front of the diff. moving up and down under hard acceleration. MSA has them, and I assume most other good Z suppliers do too. It is easy to put in, and I am assuming you have already checked the mustache bar bushings. You will get some of the "thunking" noise from them if they have any play at all in them. I prefer the urethane mustache bar bushings myself, but that is just my preference. My idea is to keep the diff in place and let the suspension do the moving.

Thanks for that just have to find someone with a uprated front mounting here in the UK.

Oops, I didn't look to see where you were. Can you get parts from Motorsport Auto shipped to the UK?? They list the solid diff mount for 70-71 for 44.95 and later models are 41.95, so the price of the mount is reasonable, shipping might cost a bit though. I have never done business with Victoria so I don't know what they have. I have done business with MSA for close to 20 years, at one time I was buying so many parts they knew who I was when I called without asking my name. I recommend them to anyone with a Z, they are one of the best here in the states. Next time I guess I should look to see where people are, I'm not used to talking to people "across the pond"!

Thanks anyway I might ring them anyway to see if they ship them across the water, I would like to find somewhere stateside who would be willing to send some bits over to the uk, as some parts are getting hard to get.

Thanks again.

Hope they can help, I don't see any reason they couldn't ship it to you. They use Fed Ex Ground here in the states, don't see why they couldn't use Fed Ex to send them over there. You could e-mail them at their web-site (www.zcarparts.com) to find out. Good luck.

BTW, nice Z. even if you do sit on the "wrong" side.

Actualy we sit on the right side!!

I would check to make sure everything is tight first, front diff mount, diff/mustache bar mounts, and mustache bar/frame mounts. I though I was experiencing the classic Z diff area knock once and it turned out to be a loose nut where the diff mounts to the mustache bar. I didn't figure this out until my mustache bar broke just around the bolt!

Although I don't know if it is the front diff mount in your case I have been running a solid front diff mount for 10 years. I bought it from Arizona Z car for $30+ dollars and can say you do hear a little more drive line noise but it is not enough to bother me ( and I don't even have a working stereo in my car). Of course I am the type that doesn't mind having to listen to the motor either!

I drive on the left, wrong, side although my wife says I drive from what ever seat I am sitting in!

Have fun!

That's the good thing about a two seater, not too many choices!!!

I can't say anything about where you sit, I've been kicking myself for years for not finding a way to by a Fairlady a friend of mine was selling, I might not have been able to shift with the "wrong" hand but it sure would be nice to have that car in my garage right about now!!
