2.3L ('83-'97) ‘94 manifold to downpipe (converter) bolts.

Cant seem to find these things, I assume they are metric like the rest of the engine, My original manifold has rusted, broke off bolts in them, the junkyard manifold didnt come with any, I went to 3 local parts stores with no luck. Looks like a coarse thread. Im considering just using long 3/8” 2-1/2 long bolts and call it a day. Anyone by chance know the dementions? Rural king has a good metric hardware stock. I have some compression springs that will work. Dont know why the rock auto kit came with 2 sets of converter to midpipe hardware but no manifold to converter hardware.

I'd probably just drill them out and use long bolts with nuts, lockwashers, anti-sieze, etc.

I think that they're M10x1.5 thread.

I'll try to confirm that tomorrow.

10 x 1.5?? should be some in the Help section.

exhaust manifold studs don't always have full depth threads, they go in tight.
anytime I've run a tap thru the manifold holes it cut quite a bit of metal. and rust
