Final installed the tail drive shaft coupler on main trans after machining a flat for the bolt to tighten against.
I decided to go ahead and use the simple tubing coil, oil cooler that comes with the kit for the main transmission rather than buy an after market cooler. Test fit the cooler in position under the back of the main tank and reshaped it slightly so it would fit between the frame tubes. Used short peices of clear fuel tubing as zip tie stand offs for securing the tubes to each other in 7 places, this really stiffened up the entire coil.
Bent the inlet tube into position to mate up with the oil pump output fitting on the trans and cut to length. Test fit the left fuel tank to determine clearance with the inlet tube since it is a tight fit.
Bent outlet tube to position to mate up with the filter inlet on the other side of the trans.
Removed the coil and installed the flare fittings on each end then polished the tubing with Purple polish to shine it up a bit.
