Prc is a different pattern then the standard three bolt cassette .
No where near as close as it currently is .
The chassis looks to be the industry standard three bolt .
The fact his old ones don't match the new ones leads to improper manufacturing .
Again that's a coyote or coyote type chassis by the front end design .
A standard three bolt should work .
As Al stated you need too measure much more accurately or return/modify .
