90 gsx, is my motor a 6 or a 7 bolt?

Im sure this is a dumb question but im honestly not sure. Its a 90 gsx.

From what ive read it seems to be a 6 bolt.

It's a 6 bolt unless it was swapped for a 7 bolt (unlikely). From 89 through 92.5, all DSMs were 6 bolt engines. In the middle of 92, they swapped to the 7 bolt design.

Thanks a lot.
