Upper to Lower Intake Manifold Gasket question

Why are they listed from 85-88 and 89 to 92?

I was just going to order Mr Gasket MRG-146 for my 1991, but the Summit page says only 85-88?

Is that correct?

The cold start injector was deleted in 1989. So the gasket will be a little different. You need the gasket set for 89 - 92.

gotcha Thanks!
Should not make any difference, as there would be just the hole in the gasket were the cold injector was, no biggie!
