I was talking to a guy a rare parts and he said they don't carry the 29.4 inch wide center link.
I'm not really sure what you're talking about, but I can guarantee you the one I suggested is correct for your car. I've used 2 of them on my 70 Canadian Pontiac's, a Parisienne and a 2+2. Same as your 68 Parisienne.
that's the part I ordered three time and was 25 so inches mine is 29.4 inches, its all better now I built my part in my shop the car has perfect steering now. RARE parts confirmed my part and said it would be custom part had to be built and explained how they rebuild them and I just did what they said and now good to go.
THANKS FOR ALL THE HELP!

Just out of curiousity I went out and measured center links on three 68 Parisiennes in the yard and they are all 29 inches pitman arm to idler arm. Measured a 68 Impala too and it is 29 inches. They're all easy to measure because the engines are out. Measured a 66 Catalina for fun and it is shorter.
I'm re-doing the steering, suspension & brakes on my 70 2+2 convertible this summer, and I've got a new in package Rare Parts 25794 center link. It measure 28-1/2" pitman arm to idler arm centerline to centerline.
Same measurement on the centerlink I pulled from the 70 Impala I parted out last year.
