Modifying snow plow/dozer blade for Custom

I am looking for a plow to fit my 1968 Custom 7 but it seems i may have to modify a plow that's actually available (I am in RI if anyone has one for sale). Looking for any advice, experience, and pictures on the topic of mounting newer plows to older tractors (hopefully Customs).

Thanks!

Found a plow with a flat mount plate- rigged up a little something over the last couple weeks then found the right plow on Craigslist for $50. Will post pictures of the modified setup when i get a chance.

Rhode Island likely just received a lot of snow.
Did you get a chance to use your plow?
Any pictures?

there is a sears custom 10xl with a plow made for it for 200 bucks for the enire machine Its under the Charlottsville, Virgina craigslist
