Are these Dorman replacement manifolds ok?

 

Good quality manifold gasket?

 

Anyone know what thread size and pitch these are? Looks like I have one broke off or at least missing.

 

…I’m thinking they are 8mm x 1.25mm thread

Hardware kit and manifold kit

 

Cool! …I believe 1.25 pitch is considered coarse thread.

 

I’m pretty sure that’s considered course thread

 

Thanks. I missed reading length description on Rockauto

 

I would just order that kit. Pretty complete! And notice they have loctite on them all ready!

 

Well, I have a nice mess to get straightened out…not only was my manifold cracked….looks to me like the flex pipe has had it too….also, some nice person broke off one of the exhaust studs in the head before I got the car….worst possible place, on driver side, outer of bottom row, right behind the heater hose pipes…I’m just lucky like that. ….and it is broke off about .090” below gasket surface. That last part might be helpful….maybe I can use a drill bushing that has correct outer dia. to be able to pick up the center and drill it (if I can figure out how to get a drill on it). Good news, it dont appear to have been leaking by in that area.
Is there any way to get the heater hose metal pipes out of the way?
