I was at my mechanics working on it.
He picked them out of a bin he had saved up from working on cars for several years.
Anyway there were M8 1.25 thread on both ends.
I am guessing they were 2 1/2" long total.
Ones I had gotten from sears hardware were about 2" and too short for the huge flange on the Mease downpipe.
The cool thing about the studs he used were that they were smaller on the end the downpipe you fit over. Allows for a wrench to pull them out or tighten them in. Also makes sure you don't fubar the threads when starting the downpipe over it to align the thing.
Still needed a couple of taps with a rubber hammer to get it on straight due to the precision housing on my old PTE51.
Taps were light however and it went right on as the tolerances are real good when the downpipe gets near the turbo housing.
A bit harder to corkscrew the downpipe in there with studs sticking out of the turbo housing, another thing for it to catch on.
Lots easier with studs for sure!!!!
We did joke about making up a kit of 4 studs with nuts and neverseize and selling them on Ebay for $29.95.
If I can get my linelock installed on saturday for racing sunday at Englishtown I will ask him if he knows what brand and type the studs are.
