Well I believe the 3 6 bolts I had in my garage all had a backwards 7T3 on the block. The 7 bolt was something entirely different.

You can pull the timing cover and find out whether or not it has the provision for a crank sensor on the front case. Also the oil pan is different, it has a notch in the front of it.

The VIN # should be stamped in the block on the passenger side, upper left corner, just below the head. It is very small letters and numbers and you may need to spray some cleaner on it to see it. The 10th digit is for the year. 1990 would be an L. 1991 would be an M. If you have an N for the 10th digit, it is a 1992. I'm not 100% on this, however, a 1992 could be a 6 or 7 bolt.

There is a way to tell a 6 bolt from a 7 bolt by looking at the oil pan. I don't remember the differences, however, you should be able to find out about it on this site.
