Accidentally ordered a big box of these for use in my EFR kits without reading my R&D notes carefully enough. Our drain lines use a large hydraulic-style fitting which fouls the bolts. Smaller Earls/Russell/Summit-style -10AN fittings will clear this just fine.

Normally ~$25 online for each one, I'll ship them to you with an ATP turbo drain gasket for $17/ea.

No need to reply or PM me, simply place your order on the website.
