will theses K-members work..

From '63 to '66 all the K members were the same. The only difference was the engine brackets and mounts. '67 to '72 used different K members for slants, small blocks, and big blocks. The '67 K member used a one year only idler arm. '73 to '76 used the spool mount K member and was different for slants and small blocks. The '67 to '72 and '73 to '76 will interchange if you use the same year range steering box and linkage as the K member. It's a lot easier to get a swap mount kit than it is to change a K member.
