Perkins Holset H1B

[Goldenstar38]

I can't believe I have to ask, but no one seems to know.
I called TAD and they did not know or could help me.
I need 4 new exhaust studs to attach my exhaust elbow onto my Holset turbo and cannot determine the thread size or type.
Anyone happen to know?
Very much appreciate any help one can offer.
Sincerely,

Holset is Cummins, try them?

My parts manual list them as studs p/n 0826439. Less than $10 online.

I believe they're just run-of-the-mill studs, one end fine thread the other coarse. I forgot what size they were, 5/16, 3/8 maybe?

I just brought mine to a local bolt dealer and he matched them up but the will need to be longer since the elbows are different!

Fantastic! I appreciate all the information. Very much.
TAD had no idea, I did try Cummins, but they do not use the same stud system the old Holset uses. They simply clamp on.
I'm going to look for the OEM type studs first.
Again, thank you all!
