Q: I have cracked manifolds on both sides of my 3.8 and would like to purchase a new one. I found your site said they were replacement manifolds part number 161230 mfr number omc-1-3857656. My question is, will this manifold work on both sides or do you have a left and a right? A: These manifolds are NOT a direct replacement for your original manifolds. They will bolt up to the block and you will need to order risers part number 46930. You will also have alignment issues with connecting the exhaust hoses and need to do some 'fitting'.
