Hi, I’m trying to put a new front flex pipe in my malibu since the flex pipe is leaking. Bolts are rusted and the space where the flange connects to the manifold flange is so tight that you can’t get your hands in there or even the socket on the bolts. Anyone changed this out? Probably gonna end up taking to the mechanic since it looks like you’d have to take apart a lot just to be able to access these bolts. Just seeing if there’s an easier way? Thank you.
