What are you guys useing for front end parts on these frames??

Centerlink
idler

there are some differences between the years Im wondering if there was a problem in 73 and they fixed it for 74? I know the idlers are different part numbers.

Thanks

I'd like to know, also. I bought all new steering gear for my mod and the left side of the drag link is too high, and the inner tie rod mounting holes on the drag link are not centered to the lower a-arm holes.

Tilley,

which side is high the idler or pitman??

a 73 idler drops down 1/2
74-77 drop down 3/4

I cant find a spec on the pitman though, my pitman is straight and I think a stock one drops down, which i threw out when I was stripping the frame.

what got me concerned is the idler has a really small hole compared to my camaro idler, so i was thinking the camaro centerlink end must be stronger?? the centerlink measurements are only 1\4 different between a camaro and a chevelle.

I have to special order in the parts, I wish I didnt throw the stock stuff out now,lol.

It's high on the pitman arm side. I did'nt realize there were differences in the '73-'77 years. Are there any differences between the models,i.e.-Cutlass, Regal, Grand Prix, Malibu, etc.? My stub is a '75 Chevelle, so that's what replacement parts I bought, drag link and idler arm. I replaced the steering box with the quicker 14-1, but used the pitman arm off the box that was on the stub. I'm beginning to think O'reilly's gave me the wrong stuff.

Centerlinks are all the same, '73-'77(DS808). Idler arms differ, '73-'74(Moog K6149), '75-'77(Moog K6152). Can't find any info on the pitman arms.

I remember before tossing all my stuff of the frame. the pitman arm was curved and went down I think.

I thought it was all the same as a camaro and planned to use all my old cars stuff, and spares.

My pitman arm has a small bend to it, definitely not straight. I'm gonna buy a '73 Idler arm and see what that does for the set-up. Wish I could find a '75-'77 chassis in this area I could rob the parts off to compare to the store bought ones. Like you, I tossed all the old stuff before buying new.
