There's no "correct" placement in the sense that there is only one specific place they must go. Put them where it works best for you - add a decent backer plate.
Ummm.... I could be mistaken but I don't believe he's asking about the "placement" for the cleats, it sounds like he's asking for the part number for a stock "replacement" cleat? Which from the catalogues I've seen online, they only seem to go back to 2004, so that's about the closest that I can get you. That being said, a 2004 Grady White 232 Gulfstream should be a part number of 10-283 for a heavy duty cleat in an 8" size for the "replacement" part number. The first link is for a used cleat, looks like they're selling each one separately, the second link is for a brand new one, of which it looks like they have a few for sale. The third link is for the 2004 parts catalogue, and yes I know your boat is a 1994, but as mentioned that's the oldest one that I can find online. Good luck!
