Fair value for 73-76 spool mount v8 k frame

This is a bolt in piece for you 69' Dart. WITH the Schumacher mounts.

Don’t they have conversion mounts for biscuit V-8 K-members and /6 k-members?

I why would you go outta your way to buy a k-member you still have to buy conversion mount to?

I’m not up to speed with the conversion mount offerings
