You say that you have a 68, are you switching everything to the Long water pump of the '70 engine ? I ask because if you do this, everything must be switched to that of a 1969. You must change all brackets AND pulleys as they are different with a short water pump and a long water pump. You should have installed a Short water pump and used all your 68 stuff. I fail to see your problem in the pictures. The cradle bracket, pivots on the water pump, away from your timing chain cover. Does your car have a/c. If it does you need a two groove pulley on your power steering pump. The power steering pump is different between a '68 and a 69. You have to change your pump too. What you are attempting can be done, but it'll cost ya !
