A cradle from an 85 through 87 will direct bolt into your car and rear suspension where as an 88 cradle will require all new rear suspension parts. Therefore the least expensive way to make the cradle swap is to use a cradle from 1985 to 1987. I have two of them here in my workshop in Elfers, FL 34680. These are both out of 87 Fiero GT's, one has been power washed and steam cleaned then sandblasted and given a light spray can coat of paint to protect it against surface rust the other has just been power washed and cleaned up. Both of these are rust free and are available. Either of them could be shipped to you however The shipping may cost more than the cradle itself. Email me at LHUBBERT2@BRIGHTHOUSE.COM for pix and pricing. Also I have quite a few people who stop at m workshop and pickup their needed parts with no shipping charges.
