K frame ID

Hey guys

I have a 72 duster that eventually I will be putting either a 360 or 408+ stroker in and found this K frame local and wondering if you can id as 67-72 or 73+

also any thing pop out at you guys condition wise?

haven’t done an a body v8 swap so new territory for me. The other dusters I’ve had with factory 318/340 cars or were converted previous

also any opinions on the slant to 8 k frame adaptor mounts available by Schumacher? Anyone used them? How do they fit and work with a moderate HP small block

thanks

JR
