You, sir, are a life saver ! Thanks for taking the time to look this up in the MPC. I was assuming that since the 66 linkage was a B suffix, then the 67/8 linkage would be a C suffix. Wrong ! Actually, the 67/68 is an A (must be common with an older linkage). It also shows me that starting in 67, the 6 and V8 linkages are the same (also very helpful). Thanks again.
