[V8Vairs] MTF,and gear oil..

[Tom Zimmermann]

..with my power-train "in", I want to add the lube for the trans-axle..I didn't drill the hole for oil transfer between the cases-on purpose- as I want to run the 'newer-car' manual trans oil in the Saginaw,but keep the 80/90/140 diff lube ..my only concern is if the shielded rear mainshaft bearing will keep the different oils from mixing..any thoughts??..Tom Z..
