Blade adapter help

I'm doing a engine swap and need a 7/8 shaft blade adapter with 4" top to bottom length to get blade closer to bottom edge of deck. Any part numbers oh wise ones.

Since you supply us with very little info, it is impossible for us to even make a guess. We don’t know the type of blade you have, Star hole, round hole and thread size in the crankshaft, length of shaft extending out, etc. Don’t know the brand of mower or model or why you are replacing the old adapter? If you are trying to swap an engine on a different deck, this is not as simple as getting a different adapter. Adapters must match blade and crankshaft. Best thing I can tell you is to google search blade adapter images and do some investigation, which we would have to do if it can to us. Can’t just pull one off the shelf.

Sounds like a Frankenstein project.
