Dunno. They were on the Verde when I bought it. I think that the PO installed them and he did not have it for very long before he sold it. The car has done 15k miles in the 4 years that I have owned it. They operate smoothly and show no signs of wear.
I think it is due to the different torsion bars that the Milano have compared to the gtv6. As far as I know, Milanos and later gtv6s (1984-86) have longer torsies so they have specfic shocks, while alfetta gts and 1981-1983 gtv6s have shorter bars and then have specific shocks.
I have a 1982 alfetta gt and I´ve been searching for good used shocks (Koni or Bilstein) and the ones I have crossed with are for Milano/later gtv6 and had to let them go although I recall that some have fitted them in earlier cars.
Recently I let go a NOS set of Bilsteins very well priced
I asked on ALFAGTV6.COM • Index page and the indication there is that the Milano shocks have a bump stop on the shock itself. The GTV6 (early) has the bump stop on the body of the car. I haven't found any indication that the valving is different.
Hesitated to mention it, but Merritt said he saw one that blew, shot across the room and stuck in the wall. It made an impression on me and I didn't forget it. Bought Koni's since, and well, I'm Dutch heritage anyway.
