If you would consider this, you could always change out from the old style linkage with the large linkage plate to the newer style 3 piece kickdown correct for 340/auto cars! I did this on my 66 Cuda with zero problems! Just need the linkage, the bellcrank that mounts to the trans, and the newer style throttle cablmount with the upper bellcrank! They used to sell it all in a set for $35, probably a little more now!! Just look for "340 3 piece Kickdown Linkage", I think I got mine from Penstar Productions! Geof
