I have the banjo fitting from an older USDM GTE manifold, however, it is a top mount fitting with a secure hook on it.

I am looking to install a fitting on the back of a JDM GTE manifold to hook up to the SC300's brake booster line. I have read several posts on the Supra forums and google searches and they all seem to have inconsistent sizes (i.e., -6an, -4an, etc...).

What I am trying to figure out is what size both ends of the fittings are (the screw end into the manifold, and the slip on end into the brake booster line). I want the fitting to point directly towards the back of the manifold rather than sideways.

Any help would be appreciated. Thanks.
