Sold the Duster i was going to use this in.
Package Deal $1450/OBO. Will ship on your dime to lower 48(Alaska, Hawaii and Canada too, but that's a pretty penny!)

Asking price is $1500 for car and all parts I've collected for it(not parting it out!)
Here are some basic details.
1973 Plymouth Duster original /6 clean CA title in hand.
Currently has a 360 and 727. Previous owner installed using early style K-member and biscuit type mounts.
No "major"...
Your welcome! Just so you know, Brewers performance sells both the bellhousing and the bearing retainer. Give those guys a call, they should be able to tell you whether or not it will work.
I have a suggestion that may or may not work, but if I was in your situation I'd at least look into it.
The 5.125 bearing retainer has a bolt circle of 4.16 inches
The 4.807 bearing retainer also has the 4.16 inch bolt circle
You might be able to use a big block bellhousing with the 4.807...
Those look like truck motor mounts to me. Depending on the year of your car and Kmember you have you'll either need the spool type motor mounts for 73 and up kmembers or the biscuit type mounts for 72 and older kmembers.
