KH Discs vs 73+ Discs

I talked with my friend with him today. I told him more about the positive and negatives of both setups. He seems to sway more towards the KH discs as they'd be cheaper for the short term. I'll most likely sell him a lot of my extra parts (0.87" T-bars, my old 7 1/4 with better gearing and larger drums, my '71 Demon front end parts, etc.) to help him out and just cut him a deal. I'd still have to get rid of my 8 3/4 and 273 leftovers plus whatever comes back from the Dart.
