You'd be best off saving up for some new ones. Why go through all the trouble putting in questionable old crap? Seems like they should have equal resistance in and out.

They shouldn't stay compressed on their own. Should be hard to push down and then they should extend back.

You're local autoparts store should be able to source soem for you. If not try Re-Speed, Koni, or Tokico.

When I was getting my tokico blues, respeed was the cheapest, unless you have a friend in the auto parts business that can get you stuff near cost.

I think I am right on them being blown, I have never seen any that stayed compressed, but you may want to wait till someone else hops in here.

Any gas-charged cartridge should slowly extend to full length after being compressed, smoothly and without gurgling or jumping.

The old, early, manually-refillable reservoir-tube struts original to the SA's didn't do this, as they weren't gas pressurized, but those are damn rare to run across now- -almost all have been replaced with the much more reliable and better performing gas-filled cartridges over the years.

Gas-filled shocks & struts first started being sold in the early 80's as I recall.

FB strut cartridges are still pretty easy to come by. SA fronts are a little harder.

It is easy to modify an SA to fit FB struts. Slightly drill out the top plate to accept the FB strut end. Then drop a LARGE nut into the bottom of the strut housing to "make up" the slack. (Something about 1/2 inch thick) Big nut, piece of steel, large washers, anything....it really does not matter. You just want to make sure the top strut housing nut tightens up snug.

As an added note, make sure whatever is used as a shim mates to the ridge at the bottom of the insert. A small nut that fits inside that ridge may damage the strut.

I'll be looking at doing this if the SA-sized Tokico Blues I put in the front back in May of 1995 ever actually fail.

Still working just fine, 14 years later...

So are they blown i thougth a shock should never be able to fully decompress?

Yeah, 'fraid so; gas-filled struts (which the KYBs are) should always slowly & smoothly self-extend after you compress them.

If they don't extend on their own, they've lost their internal gas pressure.

Shocks/struts are filled with an oil based liquid. Then most are charged with an inert gas which keeps them extended. The original front struts were rebuildable and never had a gas charge but now days it's easier to simply drop in a new carteidge that is gas charged. When the gas seal is lost, a shock/strut can rest at any position while laying on it's side.
