Missing & Broken Turbo DP Bolts / Studs

Only have had the MSP6 for 2 weeks ( 3 not counting the week at the shop ).

Previous owner / dealership took the motor out to do the clutch. and who ever did the work does not need to touch cars ever again. They did so much wrong, and im paying to fix it.

Currently Im down to the exhaust leak, which I have found that I am missing 3 bolts / studs from the turbo to the down pipe.

One is broken off it appears, but either way, I am trying to find out what the bolt / stud size is so I can buy some... there are 5 total, but Im missing 3

I have googled for a couple of days and have not found an answer.....

 

Dealer can get them for a fee, lol.
I thought Edge Autosport had them, but cant find it
SU has them here
