As per title, I've acquired a drum of ep90 so am planning on doing diffs & t'box but wasn't sure about putting it in the gearbox as I remember someone saying it was too thick for an lt77....what do ya reckon?
you will also bugger baulk rings quite quickly,baulk rings to work have grooves to strip oil from gear cone to allow baulk ring to brake gear to allow synchro hub to engage it, thick oil is too thick for lt77s and r380s
