OK, so the problems continue. I just received the adapter plate, it states that the harmonic balancer and water pump should be off the original 216, which has already left my possession. Can I use the 261 balancer or do I need to start looking for a 216 balancer, of which I had two of, not more than 4 months ago. The original water pump I can purchase, though I have two new ones, patricks and a short pump which now I can't use. Any suggestions.
