Sorry...I missed this question. That flywheel is not for the 235. The 235 flywheel has 6 mounting bolt holes and 3 spaced dowel holes. Please see the attached image. I think that flywheel Rock Auto shows is for the early SBC models. The mounting flange for the SBC is (as I recall) 3.58 inches and the 235 is 3.875 inches, so there is that problem first off. The crank mounting flange is smaller by about 1/8 inch on all sides. So there is no precision there for you. Next you will have to have three dowels drilled to match the 235 flywheel (and get them perfect or you will shake more than Elvis at any speed since the flywheel wasn't made for that crank). And then I don't know if the bolt holes match, either. I mentioned a friend did this once. He finally got it done but when I asked him about the work he just shook his head and muttered something under his breath.
