I'm pretty sure they're metric. Why not re-use the ones that are on it now? I'm sure some purists will give you reasons to buy new bolts, but I've never had any trouble with re-using them. If they're damaged that's another story.
My 85 didn't come factory equipped with a mini-starter but the later year Vettes did. I replaced mine with a mini and used the original bolts. I had to use some washers because the mini starter base is thinner, but it seems to be working fine. Mine also had a space between the starter and the flywheel dust pan (the flat one) which I had to fill in. Hardest part of the whole job was taking the old starter off, but it was worth it.

Thanks for the inform, 89 has factory ACdelco smaller (mini) starter, I just pick up a new starter (look like ACdelco starter) and don't come with any bolts. I know 89 vette motor used metric and SAE bolt for engine. Before removed the old starter, I want to pick up new bolts, I need to know the size of two bolts fasten from starter to engine is MM or SAE .

According to Corvette Central, they used the same starter bolts from 63 to 96, which would not be metric. You might check into that a little further, though.
