i'd personally put in 15w4 C/S rated oil.
for the trans sump, diffy sump, and hyds sump ( all seperate ), you can use a utf oil meeting M2c134 spec. OR use 80w90 gear oil in the trans and diffy, and UTF in the hyds.
spin on filter will be a fram ph8a, supertech st8a, napa 1452 or 1515, motorcraft fl1a , dual 300 etc.
ignition parts for that machine will be:
