I have a 1997 F-150 with a 4.6 ltr v-8 and I need to know what the thread count and what type of bolt would work best to connect the new cat to the exhaust manifold flange. The new cat came with a new pipe clamp, but no bolts. Can anyone help with this before I take it all apart? Thanks in advance!

 

im not sure but any parts place should have those in stock. they are probably the same size for all the f series.
