.. can anyone confirm if the GTV6 and 75 3 litre gearbox mounts are the same?

The forward mounts are not the same, the 75 mounts have spacer plates welded to the bottoms. I have an explanation of this on my website, along with a description of what to do about it if you need to use 75 mounts on a GTV6.

Thanks. There is a certain Alfa spares dealer in the UK that tells me they are the same. I know the 75 3 litre and GTV6 mounts are bigger then the TS and Alfetta 2.0 litre but I am not too sure if the larger one for both cars was the same.

they are not the same, That is what greg is saying.

thats piss poor which ever dealer that is. They stopped making gtv6 mounts 10years ago.

As far as i know you can use the mounts, TS mounts are 1.5cm longer than 3.0 ones, but the 3.0 Watt have 1.5cm spacers.... so the overall height of the attachemt is the same.

The only thing that i don´t agree whith Greg is that the spacers are not welded.

all the ones i have seen are spot welded. speaking from experience, i fitted 75 mounts and i got vibration. after i took the plates off, no vibration.

3.0 75 forward mounts have 1.5cm spacer????, huh, never seen that. Do you mean 1.5mm spacer? all the euro 75 V6 mounts I have seen have a 1.5 mm spacer spotted on, 4 spot welds easily drilled off.

On all the Milano mounts I have seen the spacers have been welded. I normally leave them on and shim the crossmember to bring everything back into alignment. I have pictures and a description of how to do that here: http://www.hiperformancestore.com/guiboDSclutch.htm

Doesn't shimming the crossmember give you less anti-dive? Maybe its minimal and nothing to worry about?

I don't know, but we are talking about 2-3mm here. If it makes a difference in Anti-Dive, I can't feel it.

Greg

There's no anti dive/anti squat in the de-dion rearend because there's no torque being reacted by the de-dion beam - (well, there's a small amount of anti-squat from the front pivot being above ground level, but it's nothing like the live axle guys generate)
Would be a different situation if it weren't for the inboard brakes.

Hi all,

I just wanted to know the right height of the front transaxle mounts?

I had vibrations on my newly acquired '83 gtv6 and saw that the mounts had the plates on: I took 'em off and the vibs still were there as before (driveshaft was balanced before). Some dealers (in europe) seam to do their own replacement mounts, so I do not know if mine are still the originals from the Milano 75 or if they are reproduced by someone.....and maybe the height is now wrong with removed plates.

I've attached an image with the height: 35mm and 65mm, could these be good or do I have to adjust with the plates or with washers as described by Greg Gordon in another topic or on his website?

Thanks,
Pat

In my experience, the propshaft (driveshaft) has be pretty fuXXed up to cause vibration issues. Try jacking up the bell housing a-bit-at-a-time to see if it elevates the problem.
Also, do this - loosen all propshaft coupling bolts including the centre bearing support, tighten up rear coupling first, then front coupling and then the centre bearing support.
