Hey everyone,

Finally scooped me up a decent condition Evo 3 o2 housing for my 1g, but as you can see in the pics one of the studs at the bottom where the downpipe bolts up to seems a bit damaged.

I want to attempt to repair it by going to pick up a tap and die set, but can anyone confirm the thread and pitch size of those studs?

Some of the google searching I was doing lead me to a M12 x 1.00? But looking to get this confirmed, thanks!

Bottom studs are metric fine M12x1.25
 
I have to remind you that the E3 housing is at a different angle than most of our bolt on downpipes. It can be done, but I'm just letting you know.

Yes I am well aware. Currently running the Megan racing downpipe so I know the flange of the downpipe will slip onto the studs no problem. And I am prepared to have the downpipe altered at a local exhaust shop to get it to mount properly without hitting the t-case.
