All,

I purchased a Dynomax exhaust system for my truck (1993 F-350 non-turbo). My truck originated in Canada so there is plenty of rust to go around. The Y-pipe bolts at the manifiold are very rusted and I highly doubt I can save them. Question - does anyone have details on these bolts so I can purchase in advance what I need? Much appreciated.

Where the Y attaches to the manifold should be 7/16 inch coarse thread.

Thanks! Over the course of a few days and liberally spraying PB Blaster on the bolts and with a lot of patience I finally got the nuts off. Threads look a little flattened on the nuts so im going to chase the threads on the studs and save them.
