Topline oil pump 6 or 7 bolt?

[johnk]

I just ordered an oil pump from topline. Now the box says 89-92 eclipse on the side. But the front cover is stamped DOHC 7. I got a couple weeks before my motor shows up so I have nothing to do but worry about little things like this. Anyone know how to tell the difference between the 6 and 7 bolt pumps?

6 bolt is machined flat on the bottom(oil pan mounting area) where the 7 bolt is rounded. This is right under the crank seal where the pan bolts to it.

Yep flat bottomed so I have a 6 bolt. Thanks for the piece of mind.
