1990 GTU rear end
Does anyone know what gear ratio came on an automatic 1990 GTU ? Are these rears stronger than a na rear. This is the vin # JM1FC3319L0804292 . Any and all help would be appreciated. Thanks.

Nope, thanks for playing. Only the GTUs has the 4.3.

Read the sticky/FAQ for this section - it has all the FC specs.

If it is from 1990 GTU automatic, it should be an open 3.9.
