I found a 1970 duster v8 k member to replace my bent spool mount k member in my 74 dart sport I know the motor mounts will be the puck style will this fit w/o modifications thank you
 
The only issue other than motor mounts will be "IF" you have a factory anti sway bar. On the 73/ later K, which has spool mounts, the anti-sway bar goes INSIDE the K, and is shaped different

Of course they must both be V8 if that is the engine type

All other hardware will interchange.

The steering linkage is actually different, late, to early, but if you keep it all you can use "either group." That is, the steering box, pitman arm, idler and center link

Use whatever upper arms "fits your brakes" AKA large ball joints for disk brakes etc

To sum up, if both "K's" are same engine type, and IF you have no sway bar they will directly interchange

So my 74 steering box pitman arm idler and center link won't work on the 70 k member

I'm sorry I'm confused on this so yes all my 74 parts including everything you listed will work on the 70 k member or are you saying I will have to change all these parts to make it work
 
These will swap over:
  • steering box,
  • pitman arm,
  • idler
  • center link
  • oil pan
  • radiator shroud

Will not swap over:
  • motor mounts and motor mount to K-frame nut and washer
  • motor mount brackets. That go between the engine block and motor mount
  • sway bar setup
  • Lower Control arm will swap. But if they have tabs for sway bar, the tabs will be in the wrong place

Check these for clearance:
  • automatic transmission lines. Not sure if going from late to early there's and issue. There is an issue going from a early to a late

Note: After you swap to the 68-72 K-member. If you then want to add a sway bar in future, it needs to be spec'd for a 68-72 car.

YES they will work and NO that is not what I said

What I said at the bottom of my post:


"To sum up, if both "K's" are same engine type, and IF you have no sway bar they will directly interchange"

Let's say this a bit differently. Take an early and late BARE K member. Everything is the same except motor mount setup and the sway bar setup. Swar bar and mounting is different, and lower control arm tabs to interconnect sway bar is different.
