I will have all the clutch linkage parts from a 66 if I get the 77 parts truck,I think the 66 parts will work and I have everything including new clutch parts and a surfaced flywheel with less the 1500 miles. The 66 has a 352 and if I get the parts truck I will be installing a 460 and C-6 and woill not need the clutch parts. Jeff
