difference between these arms

[keith9291]

I am looking to buy a new idler arm and pitman arm and was on Rock Auto's website and noticed they show two different parts for each one. Can anyone tell me the difference in these?

Here is the Idler arms

The Pitman Arms

Some attach to draglink from bottom up and others from top down. Then the splined hole in the pitman arms are different sizes. All are application spacific.

Thanks everyone!

These are all suppose to be for 73 to 76 A Body with Power Steering.....I checked link from Big Block Dart and top image for both parts are the Moogs the bottom are listed as Spicer (professional grade) part.

I am assuming Moog is the Parts to go with??
