hi all. I heard some of the pros and cons but still am not sure. The poly kit is so much cheaper but i hate the noise factor. Has anyone used poly mounts for the body? Thanks Tom

I heard you could get rid of the sqeaking with poly if you greased them up bunches, and kept them greased up...but gees to me that'd get annoying having to grease everything every other month...just to get it to stop sqeaking. I may go rubber when I redo my bushings, just because I don't want to have to deal with sqeaks, and I hear poly is tougher, and rides harder...thats the last thing these cars need. Just my opinion though.

It's the sound of a performance suspension my friend. I wouldn't worry about the squeeks too much. They only happen when you don't grease them up.

You must crave the bone jarring ride, my friend. The 68-72 have solid aluminu mounts, and I just cringed seeing a pavement that was not smooth as glass. When I yanked the body, the aluminum mounts were in pieces, all of them, so I opted for the 73 & up rubber. Best move I ever made. Driving the 68 now is a joy and pleasure.

I would personally go with rubber. Mine have lasted 23 years so far.

George,

I love the car!

Replace w/ stock 73 up specially designed per Duntov, no roll, etc.. No squeaks that some earlier model owners complain about. My 77 has always been very solid even w/ FE-7.

Nice photo & wheels ! :cool:

Energy Suspension is having production probs... I've been waiting for mine for a couple of months now. I suspect it's a quality prob.

If you go to poly I suggest you try another manuf. else you'll have to wait :(

Tom 75,
I just bought my new body mounts today, I got the rubber body mount kit. It cost me $159.99 plus tax. Heck the old ones have been in there for 20 years so the new rubber ones should last a long time. Make sure you soak the bolts with lots of penetrating oil. My back mount on the passangers side won't come off because the bolt is just turning and turning. The nut must have broken lose inside. I have already drilled out the rivets and will have to get a new bracket. Good luck.

I am replacing a bent frame from my 71 Coupe totaled by the one and only owner back in 1973. He drove it up to 24,000 miles and smashed it then it was stored in a garage from 1973 to 2016 when I bought her. Anyways, I haven't driven in a Vette older than a 1977 since 1977 and I can't remember how it was. I can imagine aluminum hockey pucks would be horrible plus the harsh vibrations would tend to crack body joints. I always thought anything on an old car that had rubber replaced with polyurethane wouldn't be the best idea? My sons 78 Trans Am we're finishing a nut and bolt resto on I insisted to use rubber just as the factory did to make it feel new again. Poly's just sound like a p.i.t.a. and make for harsh ride conditions. Yes, if you love Vette's or Firebird/Camaro's we know not to expect the best ride but why not upgrade a bit with you C3 prior to 1973? Anything would be an improvement to metal pucks between your body and frame but unless you're a hardcore performance junky I'd think rubber is best. I read 1973 GM improved interior noise by 40% I would think a lot was credited to the body mounts?

Hi l,
16 years!!!
Might this be a new record?
Many folks who have 68-72 cars like how their cars ride with the aluminum spacers….. sorta like a Corvette.

poly body mounts do not make noise. they don't move.
Poly suspension bushing will make noise if you do not lube them on installation.

And that makes technical information invalid? Why point this out? Is the information no longer valid?

[QUOTE=iwasmenowhesgone;1594678102]Why scold mike, how does that help?
Why did he post what he did?,
Because the forum has a rule about reviving old threads, they would rather a new thread be started,

What's kinda neat is that we can pick up a 16 year old conversation and it is still completely relevant. I had no idea of the time gap until it was pointed out.

And to be honest - the ride difference between my '72 LT-1 and my '73 L48 (both convertibles) isn't really all that noticeable.

Lamborg, please start a new thread on your topic rather than reviving a 16 year old thread.
