Got the 740 back from Morgantown Saturday night. Now I am replacing the front end of the exhaust system.
There was only one stud at the collector when I purchased the car. The other 2 were thru-bolted. I'd like to put new studs in, so I cut off and drilled out the remaining stud, and two out of the three holes still have threads. There is one that had been drilled out some time in the past leaving no threads.
Stud size I think was about 10 mm, from what I measured. I would like to tap the manifold 7/16 and put new studs in. Does anyone know where I might locate a stud that's 7/16 thread on one end, and 3/8 thread on the other? Reason I'm leaning towards English threads is I have an English thread tap and die set. I measured the clearance hole in the head pipe flange and it's about .440, so I thought a 3/8 stud would work fine.
Any input is appreciated.
Thanks,
Kurt
