I solved this. Socket head bolts goes to turbo and center bolt goes to down pipe

It’s been an off / on project and I cannot recall the correct bolts used in AOS heat shield downpipe setup? Assume socket head goes on downpipe and smaller bolt goes on left? Can’t recall where the middle one goes to as I had all three grouped together in the same bin.

Another one that looks similar to original and measures 2” same center hole to center hole https://www.driftmotion.com/ProductDet ... 0&CartID=1

Roughly 1mm. New one on top… used one on the bottom.

Thanks Tom and John. I ordered them off LN Engineering. Different color than pics on-line but same dimensions as old one.

How can we donate to this endeavor?

Where might one find a turbo oil seal for Vitesse stage 3 turbo?
