Which center link?

I tossed all of my old steering parts earlier this year when I started all my motor swap. I see now that I’m about to order replacement parts there are two different size center links for the 66 A-bodies. Does it really matter which one I use as a replacement as long as it has matching tie rod ends etc? I’d think the thicker center link would have less flex for the big tires I’m running up front. Anyone? Thanks

 

I keep seeing two sizes listed everywhere I look. Wasn’t going to buy through RA for this stuff.

 

Not sure on the 64-67 vintage, but the 68-72 did also have the same thing here.. On those, you can use either, the thin stuff was used on 6 cylinder cars, the V8 cars got the thicker components. But the holes in the parts and the steering arms are the same taper size.

I would suspect it is the same with the earlier cars.

Get the 7/8" center link. There were some applications which used the smaller 13/16", especially in 1964.
The Moog part number for 65-67 is DS740. It's been discontinued but some manufacturers still use that number.
Moog has a different number for 68-up, I don't think they are interchangeable.

64-7 centerlinks were hard to find 10 years ago, now there are several sources.
What do you guys think of Proforged parts? They're part of the Holley family:

Check out proforged. They have everything available and it's excellent quality as well as made in USA. Summit carries it.

 

Speaking of Proforged.... do you guys think their extra tall upper ball joints are a worthwhile mod? It's kinda like using taller spindles to improve the suspension geometry. They're 0.50" or 0.90" taller.
Hey Bob, it's nice to see you're back to using the Nailhead motor mounts!

 

I've used their 0.50" taller upper ball joints and it makes a nice difference in camber gain in turns. Coupled with additional positive caster in the alignment, it makes a huge difference in handling.

 

That's an older picture. I've been back and forth a couple times since then.

 

I used proforged tall ball joints in my uppers and will likely do their standards in the lowers. Right now I'm trying to find a disc brake conversion that doesn't give me more offest. CPP does a 13' setup based on C5 spindles and sealed bearing but can't ever get anyone there to answer a phone that's knows anything.
