IDI turbo to exhaust manifold bolts

[mammonista]

I have a mid-90s  AAZ motor that I bought aftermarket in about '01. The turbo attaches to the exhaust manifold with four 8mm -12 point bolts, two that are 27mm long and two that are somewhat longer. I've lost one of the 27mm bolts. Anyone have a spare or know of a supplier for these things? I'm thinking they're kinda unique.
