1970 DUSTER 440 4spd 8 3/4 posi

The breaks run '63-'66, '67, '68-'72, and '73-'76.
'63-'66 used a different center link for /6s and V8s. Also had the small sector steering box. '68-'72 used the small sector steering box as well and the same center link for /6s or V8s. The '67 used its own idler arm so I put it in its own category. Every thing else was the same as '68-'72. '73-'76 used the large sector steering box and linkage was the same whether /6 or V8. I think the pitman arm was different for power or manual steering in those years. NAPA has a different part number for each application.
Good rule of thumb, use the same year span linkage as the year of your steering box. The center link swap is only needed if you are dealing with a '63-'66. In 1976 I dropped a 440 into a '76 Feather Duster with no steering changes and no clearance problems. Still a nose heavy pig though. Just make sure the oil pan has the notch for idler arm clearance.
Hope this helps.

This does help I think. after I posted the original message I whent out to the shop and started removing a spare stearing linkage from a v8 K frame that i had, then I removed the linkage from my car, and I tried to install it.

The difference between the linkage is this...

On the 1970 /6 linkage the center link was on top of the idler and pitman arm.

On the 1973 V8 linkage, the center link was below the idler, and pitman arms.

So what you are saying is that I should be ok with the /6 linkage because it was all the same in 1970.

I think this is true because I have hade the engine in about 4 times, and it only hits the nuckle when you turn the stearing wheel all the way to the right. The oil pan I have is a very deep one in the center, but it has no notch on the side. Would I be able to heat it up and bend it in a bit?

I know that wouldn't be recomended, but I really am trying to keep this a bidget build. I still have the wedding to pay for right.
