'68 383 Barracuda idler arm/center link clearance

thanks all for input -I've see the 893 and 187 and to me they look identical to 699...notch is same - am I wrong on this?. A far as shimming, wouldn't I want to do both sides same ideally? how doable would it be for a shop to take a new one and cut and weld as needed? probably ridiculous $ ....
