can you tell me if this t top has a latch or pin mounting system just by looking at this picture.. thanks!

Looks to be a pin mount top, no trim on the edges so it shouldn't be a hook latch top.
if it's off an 1989 it should have pin latches, my '88 has small pin t-tops.

It looks like it is the pin type.

Tis the pin type, I have the same exact T-tops

thanks for the info i really needed it.. here are some more pics just to make sure..
