Here's a shite drawing The two here bits is where the lambda sensor can go but the screamer pipe is in the way of both I will either have to bend the lambda Sensor or find a shorter one it won't screw straight even with the screamer not attatched to the gearbox
Also give the bolt a good grease up wd40 or something see if it will screw in smoothly, I used some bolts out of a saxo a while back which did the job as pretty much all euro cars have the same threads
