Front end rebuild parts Interchangable ?

dazedand confused said
I have a 1965 dodge dart originally a slant6 suspension car . im upgrading the suspension to disc brake parts from 73-76 abody cars. I'am using my 65 lower control arms and 74 duster spindles calipers and 11" rotors and 74 factory upper control arms. I always use parts made for my year of car but noticed front suspension parts are getting harder to find like the pitman arm? Can i use 67-74 pitman arm?? The only pitman arm for my dart i've seen brand new is by a movtech and doorman? Im worried that there built cheap and only last maybe a ywar or two? This dart will be a daily driver and i want parts that last. Is the 67-74 pitman armis a different geometry? I'm up grading to a v8 and will be using a V8 drag link instead of the slant 6 drag link. What do you think or any questions? Let me know thanks

Don't expect to use the Pitman Arm from anything 1967-up. You are working with the early-A platform, of which the 1963-1966 cars have parts in common--and use a different drag link than '67-up. The part number (MOOG K7074) states application for a '67 Dart, and other A bodies up to '72--but NOT lower.

I have never put a '65 & '67-up Pitman arm next to each other but I expect you'll find significant differences (the approach to the center link, the clocking off of the steering box sector shaft, etc.). If I couldn't get a MOOG front end part, I would probably get the Dorman part instead, & just inspect it for wear every time you crawl underneath to lube the front end.
