Not sure on big block, but it's the same centerlink all 67-72 slanty and small block V8. Thanks for the kudos. Just find a 68-76 slanty K frame that's ate up badly w rust. Should be plenty out there to choose from Make a jig off of it like I did, then cut off the idler arm mount. Trim it to fit, and xfer it to your K frame. Install a 68-72 idler arm. The 68 up idler arm mount bolt uses a castle nut and cotter pin. Best way to do all this is with your K frame out of the car.
