Anyone here familiar with the fittings and know the correct size?
There are a couple performance shops around here and I'm hoping if I can get the correct size I can continue with the install.
Just a tad bitt annoyed with the lack of QC.
Here's a pic of the one of the fittings they included.
The fitting on the left in the pic is what I need. The transmission line threads correctly onto the switch housing on the right and the far left threads are correct to screw into the cooler. It's the middle threaded portion that's too big.
You need -6 male flare on the end of the cooler fitting. The o-ring boss size is correct if it screws into the cooler.
If you have speed shops around, take both fittings with you and tell them you need the correct size o-ring boss on one end and the -6 male on the other.
Also, I doubt their QC is messed up, possible but not likely. They have a lot of part numbers and the only difference between some of them is both will have the exact same coolers and fans only one will have -8 male flares and the other will have -6 male flares.
