A tip I learned the HARD way concerning starters. It seems inconsequential until one is lying on his back trying to work a wrung off starter bolt out of the block. There are two different mounts from the top of the starter to the block. One is a solid cast 90 degree ell and the other is a long twisted bracket. The ell is screwed into the block and into the top of the starter housing. The bracket mounts to the starter HOUSING bolt at the front top of the starter and up to the lifter cover on the block. Use one or the other; depends on the starter housing. Some are tapped for the ell and some are not. The bracket will work on any of them as far as I know. I have both mounted on my block so they don't get lost. I am using the bracket since the starter does not accept the ell in this instance. Also, the starter mounting bolts available on the "HELP" rack at the parts house and the genuine articles are not created equally. Use factory bolts if you can. Ray
