340 4 Barrel Throttle Bracket

Hi all! I'm looking for a 4 barrel throttle cable bracket for my 360 in my 68 Barracuda. I have a Holley 4 barrel with the correct Holley throttle pin adapter (Holley PN 20-7), but I'm still not getting wide open. Please let me know if you have a 4 barrel throttle bracket available! I don't need an original one, reproduction is just fine with me. Thanks!
