slant six..is my distributor going bad?

It looks like the cylinders that have the longest spark plug wires are the ones with the weakest spark and the ones with the shortest have the best spark. Possibly a weak coil can't get the fire down the longer wires? You've changed everything else, might try a different/new coil.

If you are putting your timing light down by the plug try putting it close as you can to the cap and see if you can pick up a flash there.

i was thinking the same thing about the cylinders.. im going to try that tomorrow..you might be right its an accel coil i bought 2 or 3 years ago there cheap i might go for it. it just seems odd to have absolutely no spark on cyl 6.. thats sad. it wouldnt be the points would it? im guilty of not gapping them with a lash gauge if so would anyone know the lash gap i would set them at?
