Hi,

My 83 GTV6 suffered side impact, hence, the DeDion axle was slghtly warped(wheel had positive camber). Does anyone has a spare axle as I would like to purchase and replace the whole assembly with the Watts linkages.

Also is GTV6 axle the same as the 75/Milano TS or the 2.5V6/3.0V6? Pse any advice is appreicated.

By Gerry on Unrecorded Date:

Yes the Milano axles are the same as the GTV6 with the exception that those Milanos with ABS have a pickup mounted close to the hub area to read the sensor ring on the ABS hubs. That can be ignored of course if using it on a GTV6. I believe the Milano does use different Watts linkages as the exhaust clearance differs.

The Alfetta DeDion is also the same but requires use of the thicker GTV6/Milano center bushing. You would have to swap that if you found an Alfetta axle, but it would be wise to put a new center bushing in no matter what axle you use. The Alfetta also uses straight Watts links. The Alfettas are a little easier to find in the bone yards if you go that route. It might be helpful to provide your location in this thread as axle assemblies can be pretty tough to ship. How far out is the alignment? Is it only a fraction of a degree of some thing quite significant? I imagine the toe may be affected as well.

By Vince on Unrecorded Date:

I really appreciate your invaluable advice. I think u r correct, the toe is also affected as the left Watts linkage(the bend piece) is slightly bent so the axle is biased to the left(and the toe as well). I think the linkages need to be straightened out to sort this problem( r they of the same length?) FOr this matter, can someone advice if the central pivot swivel(Watts linkage mounting) is in the vertical position when the car is lifted on the hoist(ie wheels unloaded). I figured that if the Watts linkages are of the same length, then the swivel has to be in the vertical position when it axle is free? Currently, the swivel is biased to the left(when unloaded)

U mentioned that the Alfetta DeDions have smaller bushings...can these can be simply changed to the GTV6 type easily? If I can find a 75 Twinspark DeDion then will it definitely fit? How abt the Watts linkages?

I reside in Singapore. Thanks a million

Season Greetings

The left side watts link with the curved shape is unique to the GTV6. You can tell if it has been damaged by comparing the length to the right side link. Although one is straight and the other curved, they should have the exact same effective length when placed over each other. That is the bolt holes should line up precisely in length, even though the bars are quite different. As to where the center pivit orients when lifted, that will vary with springs, shocks and spacers from car to car so unless you're comparing a 100% stock setup (which I don't have) with another, a slight difference in orientation at full droop might not tell you much. And yes, I know of no reason that you could not put the GTV6 bushing and rings in the Alfetta DeDion.

By Greg Gordon on Unrecorded Date:

I am not so sure about using an Alfetta DeDion triangle in a GTV6, I think they are different. I do not have an Alfetta on hand to compare with but I know for sure that the Alfetta's DeDion bushing is about 1/2 an inch shorter then a GTV6's Now consider that the GTV6's bushing just barely fits into its space in the crossmember so the Alfetta's will not be a tight enough fit. Perhaps it could be shimmed to work, but then it's bushing would still be too small. Remember all the power of the engine and that of the rear brakes goes through that bushing and the factory made it bigger when they built the GTV6, probably because the smaller Alfetta's bushing will wear out quickly with the extra power. Lots of people are parting out GTV6s and Milanos so why not just get the correct part?

By Vince on Unrecorded Date:

I was also told that the Alfetta DeDion bush is much smaller than the GTV6's. So there may be a problem of adaptability.

Problem is that there are only a couple of GTV6 here(Singapore) n nobody dismantles them. So it is easier to look for the 75 Twinspark axle as a replacement. Can anyone verify that they can be swopped in respect of the DeDion bush(I reckon everything else is similar)? Or does anyone has a GTV6 DeDion to spare? Really appreciate the comments.

By Gerry on Unrecorded Date:

You guys are probably right on the alfetta DeDeon. I know someone locally here who did it as a repair for a similar incident, but that doesn't mean it was done right.

Vince,

I posted in the 75 group already but just in
case. I'll be in KL next week, I will drop by
Alfatech to see if they have a rear 75 1/2 cut.
Most of these 1/2 cut cars are from england.
Last time I was there I wanted bumpers and I
saw a few front and rear 1/2 cut 75s. Can't be
that expensive.

BTW, the Alfetta Bushing will fit in the GTV6/75
dedion but it's too short. I have the early
version of the Superpro urethane bushing in
my Milano. Seems ok, but if I had to do it
again, I wouldn't have used an Alfetta bushing.
At the time when I bought th bushing Superpro
did not make the correct bushing so that was
all I could buy.

By Vince on Unrecorded Date:

Zamani,

Yes, I got your msg. U mentioned urethane bushes from Alfabill. Do they have a URL or mail order facility?

I sincerely appreciate your encouragement. Lets hope Alfatech in KL can find us a 75TS DeDion.

Some updates on the DeDion. I managed to find a 75TS DeDion. Yes, it is exactly similar to the GtV6 DeDion in dimensions externally. However, to adapt it to the GTV6, I had to change the central DeDion bush to a thicker piece. The 75TS hub flanges(stub) are also smaller. Had to change out the flanges with new bearings....

It a tough but worthy job! Thanks for all the assistance, guys.
