I've got a driver's side coil spring seat rusted through and the spring resting on the tire. I made it home just as the tire was nearly worn through, with a half inch groove around a nearly new tire.

There is a "pull it yourself" yard in the area, but I need to know which years of the 760 have interchangeable strut assemblies. Can anyone help, and maybe give some advice on the tricks to swapping them out?

Unless you have a very early car (83-84, I think) they are pretty much all interchangeable on the 740 and 760 series cars, and maybe even on the 940s as well.

Note, though, that there are differences in hubs, brakes and wheel bearings through the range of years, some of which are significant. If you have ABS, for example, the replacement must also come from an ABS car, or you won't have anywhere to mount the sensor. There are different tone rings for the ABS, depending on year, but those are not too hard to swap. The hubs went from being one piece with the rotor, to conventional two-piece, to two-piece with sealed bearings. The first two types are interchangeable as complete assemblies (you can put a two-piece setup on in place of the older one-piece type) but I'm not sure if that's also true of the sealed bearing ones.

Your best bet is to figure out exactly what configuration you have---type of hub, ABS or not, type of tone ring if equipped---and match it as nearly as possible. It would help if you had mentioned the year of your car.

You should also take a close look at the other side---you may find that you are in need of not one but TWO strut assemblies. If you do just one, you will need to take the strut apart and install your cartridge in the replacement unit, so that it is the same age and condition as the other side, but if you do them both (and they both came off of the same car) they should match (and you might even be lucky enough to find a car on which they were recently replaced)

It is an 83, so it may be more complicated than I thought. I'm having a hard time finding the same year and model, so I will use a digital camera and see if I can compare them that way. Is there any resource that gives interchangeabilty of parts, or is that asking too much?

Thanks for all the good information and suggestions.

Only 1983 and 1984 will interchange with each other. Some of the late 1984 760s have the late style strut.

You could install a pair of struts from a later car. You car would sit about 1/2" lower, but that would probably be an improvement over how it sits now.

I own an 84 760 Tic. I've already run into this issue but have yet to actually do the conversion. My turbo was built in March of 84 so I'd think that was rather late in the model year and I too have the early style strut assemblies. Converting to the later style strut will allow you greater leeway in cartridge choices, Bilsteins, for instance. The major issue is the strut mount top plate. The old style is two studs nearly vertical whereas the new style strut mount studs are splayed. They won't go through the holes without modification. There is an excellent article on turbobricks.com detailing the conversion. Look for threads started by f!rebird. Be sure you pull both complete assemblies, spring tops are different as well. Pull from a non ABS car if possible...don't think it was standard until 91 or 92; I know my 90 is non-ABS.
It can be done...if you intend to keep the car it pretty much has to be done...there simply aren't that many 83 and 84 models in the boneyard. I'll be doing mine sometime after the June VCOA Mid Summar in Kansas. Goodluck and feel free to drop me a line if you don't find the thread.

My son's car is a 1984 760T. It has no rust, and all suspension components are good, so it will be a long time before we might think about that conversion, but good information for others.
