I have been working on these parts for a few months now. They are exact copies of the adapters on my 87 gt with a 88 cradle. The metal parts were easy to make but sourcing the poly bushings and spring isolators has been a tough task. I now have a very limited number of these adapters available. They include all the poly mounts for the spring and shocks. Buyer will need to provide shocks, coilover sleeves and 2.5" ID springs. Parts are powder coated black. Cost is $235 for a pair plus actual shipping costs.

So, these adapt an 88 cradle to early Fiero ?
Cool.
But does this fit just strut conversions ? I would do that anyway. Just curious.

These are used when installing a 88 cradle into pre 88 cars, nothing more.

I should think if you used these adapters on a pre 88 so as to move the strut forward and in ward,you would find that you have a car with more feel,better response, and better handeling over all.You would need 88 springs, for they have a total outside mesurment that is smaller.

This is a great thing here, Sluppy; I have some of his parts and can attest to the quality.

As for the 88 into early swap, the old suspension had just an A-arm to locate the bottom of the strut....That A-arm had to do everything (For-aft, lateral, and part of the toe-in control) so it did none of these jobs well. The 88 suspension has each link doing (Basically) one job, so they are easily perfected for that one job. My car is much more stable, has (Basically) no bump-steer and rides better also- Plus the 88 subframe mounts solid so it acts as a reinforcement for the chassis- makes the chassis stiffer.

It is the same situation as with the Fox-mustang four link rear vs the F-body torque-arm suspension- a bunch of links each doing multiple jobs vs a set-up where each arm does only one job.
