1 will and 1 won't the y1 book gives the manifold numbers. I will look them up tomorrow if I remember. 69 isnt the same as 70 on 1 side. Pretty sure drivers side is 70 pass doesnt matter. It can be made to fit, but the gasket flange clock is different
Cool thanks, I still have the numbers off of my manifolds. Here's what's on my car now: left # 2843992, right # 2806900. When I asked about fitment, nobody said anything about the head pipes not fitting.
I'm sure a muffler shop could custom bend apipe the right way, I was just thinking it might be easier to bolt up the Y1 head pipes myself and then hang a set of mufflers so I could get the car running.
