I pulled three threads when assembling my 2.7 7R. I have had the case helicoiled (everywhere) but in order to repair the pulled studs I had to deepen the three holes slightly.
Now three studs are a bit short. Can I buy metric studs of equivalent material? Can I use grade 8.8 metric socket head cap screws? I do not want to compromise the thread engagement in the engine, nor on the top (nut) end.
Help.
