Hi, I am new on A bodies, I recently buy a 1972 dodge dart slant six. I am thinking to swap a 318 on it. It is possible to use a 1973-1976 A body K member on a 1972 dart? or I had to use 72-down K member (8 cylinder of course) thank you.

If you have a '73 - '76 V8 K-member then use it. One difference of note would be the type of engine brackets as this later model went to the 'fail-safe' style (round insulators) which would require the corresponding brackets off '73 or newer A or B-body car. I would also measure your torsion bar diameter as the stock 6 cyl. bar may be only 0.83" so you should therefore find a pair of 0.87 inchers.

Thank you so much, yes I am aware about the mounts and torsion bars. thank you

There was a company ... Stumacher? That's not right... which made conversion kits. They're somewhere on allpar, probably on the parts list page.
Yes, thank you, I am thinking about to put a 73-76 K member because I want to make a 73-up disc brake conversion also and I want to have a middle sway bar. I know that all is a direct fit, but I have doubt about the K-member

Its a good swap but make sure you use a body spindles and not b body.
Using b body spindles will fit but itll mess up the front geometry and your well handling a body wont handle so well after.

1) 360s are kinda expensive and 318s are cheap and easy enough to modify
2) The manual disc brakes on my '74 are the best brakes I ever had on a premodern car
3) I miss the 300M’s brakes (the 300C and Dart are both a bit touchy)

Do I have any problem with the steering? I see that the pitmann and idle arm are different, do I have to upgrade to 73-up steering linkage or I can use the pre72 on the 73 k member?
