Thanks for the info on the banjo fitting, yes it has the single dual sided silver piece.
On the exhaust, that's good to know. I guess I'll get the Toyota units since there is zero room to access the manifolds in situ, I want to try and avoid issues there. I'll definitely make sure to clean up the heads and manifolds well too. I got this thing cheap enough what's another $100. Only said that about 8 times so far on this project
I'm sure you're aware, but hardware is 1/3 to 1/2 the price at a place like Partsouq. Takes a few extra days to arrive, but it's never taken more than 7 days to get from Dubai to SLC.
